Fleas have remarkable jumping ability. A 0.50 mg flea, jumping straight up, would reach a height of 40 cm if there were no air resistance. In reality, air resistance limits the height to 20 cm.a. What is the flea’s kinetic energy as it leaves the ground?b. At its highest point, what fraction of the initial kinetic energy has been converted to potential energy?
