A 40 kg child uses a pogo stick to bounce up and down. The spring constant, k, of the toy equals 8,550 N/m.
By how much would the spring be compressed by the child if she simply balanced herself vertically on the pedals of the stick? (Give your answer in cm.)
How much energy (in J) is stored in the spring under the circumstances?
