It takes a flea 1.0 × 10−3 s to reach a peak speed of 0.74 m/s.
(a) If the mass of the flea is 0.45 × 10−6 kg, what is the average power required?
(b) Insect muscle has a maximum output of 60 W/kg. If 20% of the flea's weight is muscle, can the muscle provide the power needed?
(c) The flea has a resilin pad at the base of the hind leg that compresses when the flea bends its leg to jump. If we assume the pad is a cube with a side of 6.0 × 10−5 m, and the pad compresses fully, what is the energy stored in the compression of the pads of the two hind legs? The Young's modulus for resilin is 1.7 × 106 N/m2.
(d) Does this provide enough power for the jump?
