For its size the common flea is one of the most accomplished jumpers in the animal world. A 2.40 mm- long 0.450 mg critter can reach a height of 17.0 cm
in a single leap.

A. Neglecting air drag with is the takeoff speed of such flea?

B. Calculate the kinetic energy of this flea at takeoff and its kinetic energy per kilogram of mass.

C. If a 70.0 kg 1.70 m-tall human could jump to the same height compared with his length as the flea jumps compared with its length how high could the
jump and what takeoff speed would he need?

D. In fact most humans can jump no more than 60.0 cm from a crouched start. What is the kinetic energy per kilogram of mass at takeoff for such a 70.0 kg
person?

E. Where does the flea store the energy that allows it to make such a sudden leap?
