A bicycle wheel can be thought of a uniform hoop with a radius of 34 cm and mass 1.9 kg. Consider the case where the wheel start from rest and accelerates uniformly under the action of a constantly applied torque of 0.4 N-m exerted by a force at the edge of the wheel. The torque is caused by the bicycle chain acting at a radius of 11.5 cm from the center of the wheel. (a) How long does the wheel take to reach a speed of 10 rev/min? (b) Through how many revolutions does it turn while accelerating?
