    very simple integral problem

    If I have acceleration a=-0.4v^3
    how would I integrate that to get displacement with respect to time?
    Im sure i would have to integrate twice as once would give me velocity, but im not sure how to do it. Could anyone help me out?

    Cheers.

    You're expected to know the diferent forms for acceleration eg. a = dv/dt. The form relavant to your question is a = v dv/dx .... Go back and review your class notes and textbook.
