To get some exercise without going anywhere, you set your bike on a stand with the rear wheel free to turn. As you pedal, the chain applies a force of F= 20 N to the rear sprocket wheel at a distance of r, = 5.0 cm from the rotation axis of the wheel. Consider the total wheel (I-MR2) to be a hoop of radius R = 40 cm and mass M = 3 kg. (a) Find the torque r of the force.

(b) Find the angular acceleration a of the wheel.
