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 MPa. 

(d) Does this provide enough power for the jump?
