A bicycle wheel has a diameter of64.4cm and a mass of1.90kg. Assume that the wheel is a hoop with all of the mass concentrated on the outside radius. The bicycle is placed on a stationary stand and a resistive force of125N is applied tangent to the rim of the tire.

(a) What force must be applied by a chain passing over a9.01-cm-diameter sprocket in order to give the wheel an acceleration of4.55rad/s2?

(b) What force is required if you shift to a5.51-cm-diameter sprocket?
