Starting from rest, a 1.9 x 10-4 kilogram flea spring straight upward. While the flea is pushing off from the ground, the ground exerts an average upward force of 0.41 Newton on it. This force does1.8 x 10-4 Joule of work on the flea.

(a) Find the flea speed when it leaves the ground?

(b) Find how far upward does the flea move while it is pushing off? Neglect both the flea's weight and air resistance.
