A sumo wrestler with the mass of 40 kg is jumping on a trampoline. Each push of the legs drives the sumo wrestler 10 cm higher in the air. If on the first push, the trampoline went from 8 cm below its normal surface plane, find the average force exerted by his leg muscles? Assume the trampoline is a simple spring obeying Hooke's law with a k value of 12 000 N/m.
