The velocity function is v(t)= t^25t+ 4 for a particle moving along a line. The position function s(t) is an antiderivative of the velocity function. Find the displacement, s(6)  s(3), by the particle during the time interval [3,6].

what is the derivative of 1/3 t^35/2 t^2+4t+ C ?

That's the problem. I have no idea. The question is exactly like i posted it here. I did the same thing but i realized i wasn't given a value of what it should equal to. I was hoping there a different way of solving this problem

Never mind i got it.
