A 33-kg girl is bouncing on a trampoline. During a certain interval after she leaves the
surface of the trampoline, her kinetic energy decreases to 195 J from 425 J. How high
does she rise during this interval? Neglect air resistance.

  • physics -

    KE decreased by 230J
    PE increased by 230J = mgh
    So, find h
