Question

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?
b) How can a gymnast keep a constant bounce height in a real world trampoline?

anonymous · Answer

Compare the heights from once bounce to another
energy change = m g (height change)

gymnast adds force of leg muscles to offset these losses
