A basketball player makes a jump shot. The 0.593 kg ball is released at a height of 1.95 m above the floor with a speed of 7.12 m/s. The ball goes through the net 3.10 m above the floor at a speed of 4.08 m/s. What is the work done on the ball by air resistance, a nonconservative force?

This is an energy balance between initial and final:

(mgh)i +(1/2mv^2)i = (mgh)f + (1/2mv^2)f + W
