Part A = 8.075 m/s
Part B = 0.255 m

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.
