A 25 kg child bounces on a pogo stick. The pogo stick has a spring with spring constant 2.0x10^4 N/m. When the child makes a nice big bounce, he finds that at the bottom of the bounce he is accelerating upwards at 9.8 m/s^2. How much is the spring compressed?

A pogo stick has a spring with a force constant of 2.50 × 104 N/m , which can be compressed 12.4 cm. To what maximum height, in meters above the compressed position of the spring, can a child jump with the stick using only the maximum elastic potential energy in the spring, if the child and stick have a combined mass of 36 kg?
