    This is my current question:
    ----------------------------------------------------------------
    A horizontal platform is made to move up and down with shm. according to the relationship dtwox over dtsquared (acceleration) = -49x., where x is the vertical displacement of the platform from its mean position at time t.

    Show that any mass placed on the platform will leave the platform if the amplitude of the platform is > 20cm.

    ----------------------------------------------------------------------


    Do I have to show that at some point the acceleration of the platform is greater than gravity. Is that it?
