A child having a mass of 30.0 kg jumps downward onto a trampoline at a speed of 4.0 m/s. If the average impulsive force of the trampoline is 800.0 N and it acts upon the child for 0.5 s in a vertically upward direction, then according to the impulse-momentum equation, the child's velocity immediately after the trampoline force has been applied should be O 17.2 m/s 9.3 m/s 5.8 m/s 4.4 m/s
