A very very poor one.

These problems are so much easier to write out if you do some trig to begin with. Here the 3 and the 4 are a bit of a giveaway indicating a 3,4,5 triangle. Taking the liberty of changing the d to the more usual s,

where

That doesn't get you pass the calculus however.

Velocity

Acceleration

The particle will be at rest when the velocity is zero, that is, when etc. - June 9th 2012, 03:21 PMsrhRe: Displacement of a particle
Hi,

3sin(40)+ 4 cos(40) =5 but multiplying by pi or t? - June 9th 2012, 04:01 PMPlatoRe: Displacement of a particle

I do, and yes it is!

But that's besides the point I need to learn. - June 9th 2012, 04:35 PMskeeterRe: Displacement of a particle
seems you are in way over your head ... recommend you visit the links

It's ok I think I may be close to understanding.

3 x sin(40 pi radians x time)?

In which case I'm looking for the length of the hypotenus (5) x 40 pi radians x time?

So it's simple harmonic motion? - June 9th 2012, 11:52 PMGokuRe: Displacement of a particleQuote:

Trust me I am talking from personal experience, it never pays. (Talking)

You should watch those Khan videos, the guy is brilliant.

Here is another link to the physics Section:

Yeah I have been on this website before, unfortunately I don't have time to sit through all those videos. I need to have this question and others finished today.

Ok I've got it :)

The way it was written was throwing me off, I also confused Pi with Pi radians.

Thanks for all your help.
