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