Question

A pogo stick essentially has a platform on a stiff coil spring. The natural length

(Uncompressed length) of the spring is 0.5 m long and the spring constant of the spring is 1200 N/m. A

person of mass 80 kg stands on the platform and compresses the spring by 0.1 m (so that he is about to be

propelled in to the air). At this instant, the gravitational potential energy of the person is (assume that the

reference level for person's gravitational PE is when he stands on ground without bending his legs)​

Answer 1
