Assume that all of the mass of a bicycle wheel is concentrated at its rim. Such a wheel of mass 1.2 kg and radius 30 cm starts from rest at the top of a hill 100 m long and inclined at 20º to the horizontal. What will be the speed of the wheel at the bottom of the hill if it rolls without slipping?

a. 21m/s

b. 26m/s

c. 15m/s

d. 33m/s

e. 37m/s
