a pogo stick has a spring with a force constant of 2.5 cross times 10 to the power of 4 n divided by m, which can be compressed 12.0 cm. to what maximum height can a child jump on the stick using only the energy in the spring, if the child and stick have a total mass of 40.0 kg? use the conservation of energy between elastic potential energy and gravitational potential energy. 1 half k x squared space equals space m g h space
