Formula assistance, can anyone assist?

A basketball player makes a jump shot. The 0.534-kg ball is released at a height of 2.01 m above the floor with a speed of 8.95 m/s. The ball goes through the net 3.48 m above the floor at a speed of 4.87 m/s. What is the work done on the ball by air resistance, a nonconservative force?
