A girl of mass m1=60.0 kilograms springs from a trampoline withan initial upward velocity of vi=8.00 meters per second. At heighth=2.00 meters above the trampoline, the girl grabs a box of massm2=15.0 kilograms. (Figure 1) For this problem, use g=9.80 metersper second per second for the magnitude of the acceleration due togravity.

A) What is the speed vbefore of the girlimmediately before she grabs the box?

B) What is the speed vafter of the girlimmediately after she grabs the box?

C) What is the maximum height hmax that thegirl (with box) reaches? Measure hmax withrespect to the top of the trampoline.
