but there are still some probability that it lands on the penetrating side and if that happens its kills.. an average falling bullets has a velocity of 300mps which is very dangerous..

Once the bullet attained it Maximum height, it cannot kill again , tho , when it lands on your head , it would be painful , but not serious ... Do u know the numbers of bullet that have been shot in Lagos during the period of hijacked #endsars protests ?, most of them are on the roof, some falls on people compounds... It doesn't harm...most people hear light sound on their roofs but never bother to check it , some times it's bullets being shot somewher else.

officialfestus:
then I think the principle is not for all bullets,because a gun that uses the pump action type of bullets can not harm a fly when it's falling from the sky.

yes, if the bird is very far inside the sky

Small time dem go come begin dey blow grammar say bullet when fall from up no fiti wound pesin.

Faithful007:
They are fired up to 15000 feet at 1500m/s. They fall back at 200m/s and can still be quite deadly, that's why people are killed by stray bullets.

That's scary

PaChukwudi44:
They soldiers shot into the air and all the wounded and dead people jumped up and caught up with the bullets

ibuildstuff:
If u watch the video, the soldier were not holding the gun at 90 degrees.

Bullet move in projectile direction unless in 90 degrees. Anything lower or higher than 90 degrees may likely kill someone.

You are seriously confused and probably failed maths and physics if at all you did it.

You referred me to your previous post and you have been sharing the very thing that goes against what you have said up here.

But a bullet that's fired straight up would only hit you with that same speed when it came back down if you were in a world without an atmosphere

The bolded means if the world has no air. But we have air, so the bullet cannot possibly be close to the velocity it left the gun.

Secondly, if you knew maths and trigonometry, you should know that when the bullet was shot at an angle 20degrees to 90(which the soldiers did), the likelihood of that bullet meeting someone will be at a distance of 5km or more depending on the gun.

Practically, if the soldier held the gun at a height of 1m above ground and shot at 45degrees, tan 45=1. So for every 1m the bullet travels horizontally, it also travels 1m vertically.

If the protester stood at 1m in front for the gun the protester has to be over 2m tall to catch bullet. By the time the bullet travels a distance of 5km horizontally the bullet would have been 5km vertically.

There no way anyone within 2km of Lekki toll gate will catch the bullet with its initial velocity.

Now, don't start about the projectile path because the bullet left the gun with a very high velocity far higher than gravity. A that point, gravity has nothing on the bullet until air drag reduce the velocity such that gravity will start to act by bending the trajectory into a parabolic path. Its more like the reason a plane defies gravity and flies.

So when a bullet leaves a gun, depending on the gun, for atleast 500m the bullet will be in a straight path. Before it starts the parabolic flight due to gravity.

Remember an AK-47 has a muzzle velocity of over 700m/s while gravity that returns the bullet to earth is less than 10m/s.

eagleonearth:
how is that done

Go and Google about Military Parade and see how it's done.

PaChukwudi44:

For once we agree on something.

l think bullets fired up end up. until you get fired by a bullet, you will never understand what a bullet is.

Thanks for sharing. This is enlightening.

SalamRushdie:
Bullets shot into the air can actually Fall with almost the same lethal muzzle velocity depending on the angle of fire and the weather forces at play at the time ..Yes falling bullets can kill .

ShoProperties:
We see military personnel everyday shooting bullets in the air in a bid to either scare away civilians or announce their arrival to restore sanity to an already deteriorating event, either way, most people get to wonder where the bullets that are shot straight up into the air goes to and if by any chance they can cause any form of damage or injury.

Is this not the case of people sleeping and bullets pierce their roof and land on their feet? May God not permit us to see bad thing

adanny01:
You are wrong.

A bullet shot does not travel indefinitely. Air will resist its movement. Gravity wants it to fall down. A bullet shot at 45 degrees will either meet an object or travel at the same 45 degree until the momentum it has drops to that which gravity will start to pull it down. From the moment gravity starts acting the line of travel bend towards the center of the earth. At that moment, the momentum it has cannot penetrate human skin.

Myth busters did an episode on it. Study physics, you will understand.

A bullet shot at 90degrees will be more dangerous. You will never see a trained gun handler shooting vertically in the air. The bullet will stall when it lost all momentum, gravity will return it to earth at a speed higher than a 45degree bullet. It may still not penetrate but will certainly hurt more.

Interesting and technical topic!

When a bullet is fired almost vertically into the air, the bullet would keep going upwards in the sky, while it speed reduces, until it reaches maximum height. Its speed reduces because of gravity and air drag. At maximum height, the speed of the of bullet would be zero.

For the return path of the bullet's journey (i.e. falling down), it's initial speed is zero. It's like a mango hanging on a tree about to fall.

As the bullet falls, it's speed increases (i.e. it's accelerating). This falling speed would not keeping increasing forever. This speed would keep increasing until it attains Terminal Speed. Terminal speed simply means maximum constant speed the bullet would attain while falling.

After the falling bullet attains terminal speed, it would continue to fall with that same constant speed with no acceleration.

Falling objects attain terminal speed because of the presence of air i.e air drag. So, the falling terminal speed is considerably small when compared with the muzzle speed (i.e the speed with which the bullet was fired at the beginning.).

Assuming there is no air drag, the bullet would return to the ground with the same speed with which it was fired! Deadly!

So, the bullet returns to the ground with terminal speed, a relatively small speed when compared with the bullet's starting speed.

The bone of contention: How dangerous is terminal speeds of bullets?

Bullets are highly streamlined to defy air drag as much as possible. They are highly dense so as to cause as much damage as possible. With this two factors, the terminal speeds of bullets are considerably high when compared with other objects.

Even though when a falling bullet is not accelerating, it could still be lethal depending on the weight and the height it's falling through.

Kuwaitis were having end of war celebration one particular year and their soldiers were firing bullets into the air. Falling bullets killed about 20 of the civilians who came to celebrate with them! Even though the falling bullets were falling with terminal speeds, the bullets still killed some people at that ceremony.

Summarily, falling bullets can kill depending on the type of bullets and the angle of projection. So, take cover when armed men start shooting even into the air!

Bullets fired into the air usually fall back with terminal velocities much lower than their muzzle velocity when they leave the barrel of a firearm. Nevertheless, people can be injured, sometimes fatally, when bullets discharged into the air fall back down to the ground.

Jakumo:
Several army trucks were reportedly seen leaving the massacre site, loaded with dead bodies that were either dumped in the Lagos Lagoon, or buried secretly in holes excavated by bulldozers. The death toll may well have been as high as 500, since there is no accounting for all the homeless area boys, that mingled with the crowd of protesters, to loot and terrorize, rather than to engage in legitimate protest.

then why was the the floor not full of blood?
because I saw the toll gate on Arise TV the next day. and even dj switch said they counted 15 dead bodies.
I watched 5 different people that were live on Instagram, and none of them showed dead bodies.
I saw just like 3 don't you think we would have seen the bodies before the soldiers took it away

Ok

Now, terminal velocity is the point where the force (gravity) acting on the bullet equals the force opposing it (air drag).

We are not the first to start this argument. We also have too many variables to do a simple math so lets adopt what has been done by professionals.

It has been established that the terminal velocity of a bullet is about 90m/s or more. Thats over 200mph

AK-47 muzzle velocity is upwards of 700m/s.

You can see the difference. The question is, is 90m/s lethal enough to penetrate a human skin. This question boils down to shape and size of the bullet. A pointed tip bullet should do more damage than a rounded tip. So the type of bullet is an important factor.

Also, it has been established that a bullet during a free fall does not turn towards its pointed side. It most likely lies with the side that gives it the lowers center of gravity which is usually its side. This creates more air drag and also reduces its penetration power if it hits a human.

One thing is for sure, such bullet will cause a serious bruise, or skin tear but less likely fatal even though it has been established that it has and could be lethal but the chances are slim.

Over-sabi is truly a sickness. This video was posted on this same frigging page, about a major life-threatening injury inflicted by a stray bullet fired into the sky hundreds of yards distant from the victim, yet Professor Bigi Gramma here, is still pontificating about "slight bruises".

Here is is again, in case you are partially blind.

Closer to home, I happen to have known late Mr. Klaus Ewert, a German geologist who for over 28 years, resided in Nigeria. Klaus was sleeping in his Ikeja home one night a few years ago, when BOOM, an AK47 round fired into the air so far away that the gunshot could not even be heard, pierced through the roof of Klaus's home, and buried itself DEEP inside his buttocks, causing him to bleed profusely, and calling for a late night visit to the emergency ward, where his life was saved after extensive surgery.


If such an injury from a falling stray bullet is what you would call a "slight bruise" then death itself, must be to you, a minor illness.

Who dey do over sabi? You or me?

Point exactly to where you quoted me saying the statement "slight bruise". If you can't, you are a liar.

Can you read at all? Do you not know what lethal is? Did the man in your video die?

Go back to primary school where you came from.

What we are discussing here is clearly beyond your reasoning or comprehension. I am sure you got confused reading my comment, it wasn't meant for kids.

Well, Professor of Ballistics, all I can say is that my good friend Klaus came within a hair's breadth of dying due to rampant blood loss, from a bullet that severed major arteries, after being fired into the air so far away that the gunshot was not heard by anyone in the area.

If you would have preferred that the wound had killed Mr. Ewert outright in order for my statement of fact to be accepted by your learned self, then please accept my humble apologies for that man's failure to die as you would have deemed necessary to validate my account here.

No wonder why things are the way they are in Nigeria. People see glaring facts but still choose to wallow in ignorance. Go to YouTube and see countless videos of people who died, some injured. I'm sure the injured wouldn't have survived if their healthcare system is like that of my dear country.
Op asked a simple question
And the answer is: the bullets fall back down and can be fatal.

Excellent analysis!

Those falling bullets that cause deaths most likely have speed far more 90 m/s with higher density.

Naijabad:
They defy the law of gravity and hang in the air.

Na so. The Nobel Prize will soon be awarded to several of Nairaland's professors emeritus of ballistics and human physiology.

To the professors of ballistics in da house, here is another short video clip, to explain the facts of life as they relate to falling objects.
