What is his speed as he lands on the trampoline, 2.2 m below his jump off point?

If the trampoline behaves like a spring with spring stiffness constant 7.1 * 10^4 N/m , how far does he depress it? Any depression of the trampoline from equilibrium is to be taken as a negative distance.

Part A = -2.13 * 10^-5 C

Part B = E = 1.02 * 10^-7
