A 61-kg trampoline artist jumps upward from the top of a platform with a vertical speed of 4.2 m/s . How fast is he going as he lands on the trampoline, 2 m below? The answer is 7.5 m/s If the trampoline behaves like a spring of spring constant 5.1×104 N/m , how far does he depress it? Express your answer to two significant figures and include the appropriate units.
