A girl with a mass of 60kg springs from a trampoline with an initial upward velocity of 8.0 m/s. At height 2.0 meters
the trampoline, the girl grabs a box with a mass of 15kg. The velocity before she grabs the box is 4.98 m/s. and the velocity after she grabs the box is 3.98 m/s
a) what is the maximum height that the girl (with box) reaches? Measure hmax with respect to the top of the trampoline
