Real world trampolines lose energy since they are damped springs with much internal friction. How much energy does the sumo wrestler lose on each bounce in this situation?

Question

Information I was given:
mass=400 kg
gravity=10N/kg
k = 12000 N/m

I also know from the previous question each push of the legs drives the sumo wrestler 10 cm higher in the air, and on the first push, the trampoline went from 8 cm below its normal surface plane.

I know how to get the initial energy through mgh, but what about the final energy?

Answer 1

bruh did you get it?
