A 200 kg sumo wrestler drops onto a trampoline from a height of 150 cm. The spring constant of the trampoline is 13 100 N/m.
What is the amount of displacement in the spring? *yes we are treating all the springs as one big spring
If the sumo wrestler only achieves a height of 125 cm after the first bounce what was the amount of energy lost in the springs?
Assume all of the energy was lost due to friction in the spring, what was the force of friction in the spring?
