For its dimension the common flea is one of the most achieved jumpers in the animal world. The 2.5 mm long, 0.49 mg critter can reach a height of 20 cm in the single leap.

Q1. By neglecting the air drag, what is the take-off speed of such a flea?

Q2. Compute the kinetic energy of this flea at take-off and its kinetic energy per kilogram of mass.

Q3. If a 77 kg, 1.8 tall human could jump to the similar height compared with his length as the flea jumps as compared with its length, how high could he jump and what take-off speed would he require?

Q4. However, most of the humans can jump no more than 60 cm from a crouched start. Find out the kinetic energy per kilogram of mass at take-off for such a 77 kg person?
