A solid steel sphere of mass 3.5kg and radius 13cm is released from rest on a circular-looping roller coaster track. The loop in the track has a radius of 50cm. Assume the ball rolls without slipping. You may ignore the frictional effects of the track on the ball, but include the fact that the ball loses 5.0J of energy due to the work done by air resistance. Define the floor to be h
