2. Rubber brakes can slow down a bicycle by applying a torque to the rim as shown in the figure below. If the initial angular speed is known, how could the torque exerted by the brakes on the wheel be determined (assuming no friction and a constant torque). Rubber Pad- Wheel Rim (A) Measuring how much time the wheel takes to come to rest (B) Measuring how many rotations the wheel completes while coming to rest (C) Measuring the distance from axle to brakes and the normal force between the rubber pads and the rim (D) Measuring the mechanical energy dissipated as the rim rubs against the rubber pads
