Robert is jumping on a trampoline. Each time he impacts the trampoline, his vertical momentum is altered by a resistive impulse that slows his velocity to zero (in other words, his motion stops for an instant when the trampoline material is maximally stretched). If immediately prior to impacting the trampoline his 68 kg body is moving downward at 7.1 m/s, what is the impulse that is applied by the trampoline to slow his velocity to zero? If the time required...

A girl of mass m1=60.0 kilograms springs from a trampoline with an initial upward velocity of vi=8.00 meters per second. At height h=2.00 meters above the trampoline, the girl grabs a box of mass m2=15.0 kilograms. (Figure 1) For this problem, use g=9.80 meters per second per second for the magnitude of the acceleration due to gravity.
