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
Final energy= PEfinal + KEfinal
Intial energy=PEinitial + KE initial
Solve for friction.
I will be happy to critique your work.
