*PHYSICS
A Light inextensible string passes over a smooth Pulley and carries masses of 4kg and 3kg at its ends, the masses are released from rest,
find:
1. Their common acceleration
2. Their speed after two seconds
3. The distance travelled at that time(Take g=10m/s^2)

You welcome Bhuumhite, what course?

Not at all @Chimezie...you are getting it all mixed up.

Here you go:

RESOLVING HORIZONTAL FORCES PARALLEL TO THE PLANE

Fcos30-50-mgsin25=0

0.8660F-50-63.39=0

0.8660F=113.39

F=113.39/0.8660

F is invariably = 130.93N

RESOLVING FORCES PERPENDICULAR TO THE PLANE

Fsin30 + R= Mgcos25

0.5F + R= 150 cos25

(0.5 x 130.93) +R= 135.94

65.46 + R= 135.94

Therefore, R= 70.48

Recalling Fr=₹R.............Where ₹=co-efficient of friction.

₹=Fr/R

₹= 50/ 70.48

₹ = 0.709( closest to 0.73 in the question)

That was a very good attempt I must add. You noted all the rudiments of the question.

*PHYSICS
1. A car of mass 1000kg is moving up a hill inclined at 30 degrees to the horizontal. The total frictional force on the car is 1000N. Calculate the force P due to the engine when the car is moving with a steady velocity of 2.5m/s.

A. 5.9KN

B. 6.0 KN

C. 7.2KN

D. 6.0mN

2. A car of mass 15Kg is pulled up by a force at an angle of 30 degrees on an inclined plane which makes an angle 25 degrees to the horizontal. If the car moves at constant speed with a force of 50N acting against its motion, determine the co-efficient of friction.

A. 0.60

B. 0.63

C. 0.73

D. 0.91

Try to get materials from other sources on current affairs, verbal and quantitative reasoning, as well as minor IT terminologies with cinfores included so you won't be disappointed

Too expensive joh...for here 2GB na 1200....y nah...na so d money dey rush in....

jennyblash:
try to consult your brochure and besides,is it the jamb combination or waec requirement you are asking for?

blesseenE:
for o'level, i think she should be science inclined, then score real high in her PostUTME

tolaxin:
Am I welcomed with my 214

Dunsin89:
. Guy you be ''mumu'' oh. Wetin be what about the remaining 75 questions? Don't you know how to read English or is your eyes shifting or skipping words while you read?

Dunsin89:
. Text me your own number.

DrHost:
U remember that from page 21....... Page 113 proved one of the principles I believe in

Dunsin89:
...... and what is that o bros?

estijaz:
lolxxxx,u make me laf,neva should av said my real name,datx wat av been avoiding all along,datx y I lied abt having 79,well God knows y u had to find out so soon
yea am on low cut,cut my hair some weeks b4 d exam becos na war I dey go fyt d exam hall.I love n miss my long hair oooo but I love mbbs more so I had to sacrifice it for the greater good cos it was a distraction to me
we wil surely meet one day if n only if itx God's will

jaymejate:
mathematics, physics, chemistry, geography or econs for jamb o .
if she do mathematics , chemistry nd physics, den geology go welcome her,,, GREATEST ROCKITES !!! GREAT!

juz list her subject for here so we go knw whr she fit stay

jaymejate:
shoro niyen?

Estate Management? i no tink so and i no sure. maybe he should check another skul or pick another department as in course.
or better still write out his jamb subject combo nd o'level as well to know easy better course 4 him.

hope say nor be 'she' , i trust u o.

and stop fighting us... na naija we de not Korea.

whales2020:
That is closse...u ll ;I ll,we ll enter...#believe

P0lyMath:
a friend of mine wants to defect from Imsu to uniben. She opted for estate management in imsu. She scored 204 in jamb, so does uniben offer estate management?

if no, what's its close substitute. Her combo re UOE,govt,maths & econs

Just logged on to site jamb to check my result,.... feel like crying....
Scored 43 in English.... A whole me.... It's just not possible.. considering i even tutor ppl for dz jamb..
The comprehension was a breeze.... i did everything well even the stupidd register... Am very sure cos i knew the stress i went to through in understandn their bleeped up English.. Only part i didn't do well z d oral... Don't know it n i couldn't waste my time on smth i didn't know..

Scored 69 in maths.... pheww... apart from 3 or 4 questions involving circle geometry n their stupidd line with d one mistake i made, i should score Nothing less than 80.. Am not a slowpoke, i know wat i did very well... i even did all the line equation well, matrices, AP.. everything.. I was really swell doing this maths. couldn't believe my star... didn't know jamb had their own plans.....

Scored 72 in physics.... Come to think of it.... i didn't remember d formula 4 inductance, Velocity ratio n 2 other questions.... So i ain't happy with this

Chemistry...... mehnnn.... Everything here was simple.... most of wat i was tot in yabatech in my first year was wat i saw.... ranging from fehlings soln to alkanoic acid to alkanal n d rest... was expecting atleast. 82 give or take 4 marks..

Am really sad to v prepared 4 dz fvcked up jamb only to v scored 246.....
even d first jamb i did without much preparation that got me into yct was 277 talkless of all d night reading.. preparation.. even taking students under me to tutor..

God will in his abundant mercy, punish those modafucker... May dey rot in hell... Na by force to do CBT if ur not capable of doing it..
First of all, i waited from .Thursday to dz moment anxious to c my result only to c this..
Mehnnn... can't believe m almost crying.. Jamb d better give me my result.. Wish i could call 4 my script...
