Starting from rest, a 1.8 x 10^-4 kg flea springs straight upward. while the flea is pushing off from the ground, the ground exerts an average upward force of 0.42 n on it. this force does +2.7 x 10^-4 j of work on the flea. (a) what is the flea's speed when it leaves the ground? (b) how far upward does the flea move while it is pushing off? ignore both air resistance and the flea's weight.

The drag force, fd, imposed by the surrounding air on a vehicle moving with velocity v is given by fd = cdaρv 2/2 where cd is a constant called the drag coefficient, a is the projected frontal area of the vehicle, and ρ is the air density. an automobile is moving at v = 80 kilometers per hour with cd = 0.28, a = 2.3 m2, and ρ = 1.2 kg/m3.
