The position s(t) of an object moving is in a straight line is given:

s(t)=2t^4-5t^3+t-3

a. Find object velocity v(t) and acceleration a(t).

b. find all times t when the acceleration is 0.

I have an exam coming up and I just want to practice some before tomorrow because I'm not sure how to do them at all!

Were you aware that the equation for velocity is found by differentiating the equation for displacement?

Put up your work so far and see what you get :) - May 27th 2009, 09:21 AMlisa1984wilson
v(t)=2*4*t^3-5*3*t^2+1

a(t)=2*4*3^2-5*3*2*t - May 27th 2009, 01:54 PMcraig
Your equation for velocity seems correct, I cannot read your one for acceleration though, could you take a minute and put it in the correct latex code.
