Fleas have remarkable jumping ability. a 0.45 mg flea, jumping straight up, would reach a height of 30 cm if there were no air resistance. in reality, air resistance limits the height to 20 cm .
part a what is the flea's kinetic energy as it leaves the ground?
part b at its highest point, what fraction of the initial kinetic energy has been converted to potential energy? express your answer using two significant figures.
