I have a already, please help me with b. Thank you.
A 75 kg trampoline artist jumps vertically upward from the top of a platform with a speed of 5.5 m/s. (Ignore small changes in gravitational potential energy.)
(a) How fast is he going as he lands on the trampoline, 3.0 m below?
9.44 m/s
(b) If the trampoline behaves like a spring with spring stiffness constant 5.2 104 N/m, how far does he depress it?
