Question

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 to slow Jonaz’s velocity to zero was 0.35 s, what is the force applied bythe trampoline?
