(a) The initial speed of the hoop is vi = 3 m/s, and the hill has a height h = 3.8 m. What is the speed vf at the bottom of the hill?

(b) Replace the hoop with a bicycle wheel whose rim has mass M = 3 kg and radius R = 0.5 m, and whose hub has mass m = 1.2 kg, as shown in the figure. The spokes have negligible mass. What would the bicycle wheel's speed be at the bottom of the hill? (Assume that the wheel has the same initial speed and start at the same height as the hoop in part (a)).
