Question

The resilin in the body of a flea has a force
constant of about 24 N>m, and when the flea cocks its jumping
legs, the resilin associated with each leg is compressed by approximately 0.12 mm. Given that the flea has a mass of 0.56 mg, and
that two legs are used in a jump, estimate the maximum height a
flea can attain by using the energy stored in the resilin. (Assume
the resilin to be an ideal spring.)
