    1. The problem statement, all variables and given/known data

    A girl jumps up and down several times on a trampoline( sheet stretched horizontally by springs at the sides). What will the graph of her acceleration as a function of time look like?


    2. Relevant equations

    i don't think one is needed

    3. The attempt at a solution

    I have no idea what to do!

    First try to describe the motion in words. When she is at the top of her jump, will she be accelerating up or down? How about when she is halfway through falling? And what about when the hits the trampoline? When she is halfway back up to the top of her jump, will she be speeding up or slowing down?
