Well it starts from a rest but what we are looking is already moving. It start at 0 but what we are looking at is the section from 8t to 12t

ummm but the problems is that this in not from a dead stop.

So i guess i can try and use the formula and switch it around. a=2d/(t^2)

constant acceleration =(v(t2)-v(t1))/(t2-t1) = chance in v over the change in time.

Man I am so lost. Ok i relized i used the average velocity, but what i need to do is use the instantaneous velocity? I never did understand inst. vel? Thanks for welcoming me, i loved physics in high school but so far this college physics is :confused: :mad: :cry:
