(A) dv/dt=16cos4t dv=16cos4t dt v= 16int(cos4t)dt = 4sin4t + c From the questn, boundary conditions(v,t) are (2,0) c=2 Particular solution is v = 4sin4t + 2 .........1
ds/dt = 4sin4t + 2 s = int(4sin4t + 2)dt s= -cos4t + 2t + c
Including boundary conditions, (s,t) = (0,0) c=1 Particular solution = s = -cos4t + 2t + 1...........2
B) when particle comes to rest, ds/dt = 0 (stagnant)
0 = 4sin4t + 2 t = (1/4) arcsin (-0.5) sin is negative in 3rd and 4th quadrant t= (1/4).210deg or (1/4).330deg Since pi=180deg or 2pi = 360, then Values of t in seconds are, t=(7/24)pi or t = (11/24)pi

correct

THUNDAR:
Sorry I read computer science!
I only understand programing language!

So, in your computer science, you skipped courses like algebra, vectors & geometry, mechanics, calculus & trig, differential maths, real analysis etc? Which school did you study your own computer science?

So what programming language do you only understand? You people sef.

E b luk Chinese 4 my eye una calculation.
Na administration sure pass.

ikbnice:
This is a Physics question not Further Mathematics.

Particles physics to be precise

Bros I like your type, you like wahala pass yourself! There is something you don't understand, in your first level, mathematics and physics are just preliminaries, later on in your study you do serious stuff that you will not have a single time for maths: you things say computer science na to de move mouse??

You want to know d language I know? Start with this

thanks a lot...you are very right! You nailed it! I never had further maths teacher in sec sch..but I just love solving it! Am grateful...c as u do am like sey na chewing gum! You na bahdthief!



Hmmm...but bro...na 15mins you take solve am? Hahahaha. Weldon.

@Thundar, people like you are what is wrong with education in general and the computer science field in specific. Limited by triviality, you constrain a field of knowledge into a cliche. Computer science until few decades ago was known as computational science and was under the department of mathematics. Infact, in some schools all over the world, it is a double major with mathematics. While in some schools all over the world, it is a double major with engineering, like in MIT, Boston where it is offered as computer science & electrical engineering.

If indeed you studied computer science, you had realise that all those who had a role in the evolution of computer science as a field of study were either mathematicians or physicists or engineers. Because many of the frameworks have been laid by these founding fathers and great developers, people like you are just unabashedly users of tools created.

So I ask, what are the more serious stuffs done in computer science that does not require the knowledge of maths? Even the simplest loop in algorithm requires algebra.

I asked for the programming lang you claimed you are well versed in and you link me with a copy-paste page filled with scripting jargons? Damn, ignorance is truly like a prison with invisble bars.

Lol. Due to the nature of my degree, I have been privileged to model much more complicated questions than this. To design feed forward or feed backwards controllers in engineering (I presume u're still in secondary school and aspiring to do engineering so u might not understand this for now), you will model a lot more difficult scenarios than this one. During my school days in futminna, where I graduated from, the above questions are objective questions found in general engineering mathematics for year 2 students. You're often expected to provide answers in a minute or two.

the way you simplified it is a source of motivation to me..I can't wait to start modelling...I love Engineering. Am deeply greatful. Am a fresh student...studying Mech Eng...UNN. Thank you Sir.

How far? you don preach finish? I just got back from 4days ban for posting that source code! I would like to explain a lot of things you don't know, But it seems you are MR KNOW ALL! Computer is my field, wanna keep talking? talk to my recycle bin

if dem bring programming languages now, u go still deviate....we sabi una type
