**Reiny**, Wednesday, April 18, 2012 at 8:09amUnusual wording of this question

When they ask for "average" velocity and acceleration, usually there is a time interval involved.

In your case , we are given t = 4, a specific time.

I would expect to be asked for the "instantaneous" velocity and acceleration

method:

if s = t^2 - 3t^2 + 2 (I assume a typo, since the = and + on on the same key , also is one of those a cubic? )

v= derivative of s

a = derivatiave of v

sub in t = 4
