Unusual 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
