A basketball player makes a jump shot. The 0.700 kg ball is released at a height of 2.10 m above the floor with a speed of 7.30 m/s. The ball goes through the net 3.10 m above the floor at a speed of 3.10 m/s. What is the work done on the ball by air resistance, a nonconservative force?


Final energy= initial energy + friction
or
Final energy= PEfinal + KEfinal
Intial energy=PEinitial + KE initial

Solve for friction.
I will be happy to critique your work.
