Find the particles position s at time t.

1.) when

2.) and when

I think I got the first question, I ended up with , but I don't know what to do with the second problem. Any help is appreciated, thanks.

For the second question

s''(0) = a

so s'(t) = at + ?

s'(0) = v

Can you take it from here? - Dec 12th 2010, 04:32 PMlancelot854
Yeah, I get it now, thanks.

Be careful about problem two. I would have interpreted "a= 32, v= 20, and s= 5 when t= 0" as meaning all three values are given

**at**t= 0. In that case, you do NOT know the acceleration at any other time and cannnot answer the question. You have to assume that "a= 32" means that the acceleration is the**constant**32 while v and s are given at t= 0.
