Hi Sadah_17

I'm away from my computer at the moment, so I will tell you what to do.

a) velocity function is the first derivative; acceleration function is the second derivative

b) Into the first derivative, sub t=3

c) You can do this the old fashion way by finding the vertex of the displacement function (s(t)). Since it's a quadratic, it should be easy to do

Does that help?
