Physics

A bicycle wheel has a diameter of 63.0 cm and a mass of 1.74 kg.Assume that the wheel is a hoop with all of the mass concentratedon the outside radius. The bicycle is placed on a stationary standand a resistive force of 117 N is applied tangent to the rim of thetire.

(a) What force must be applied by a chain passing over a8.99-cm-diameter sprocket in order to give the wheel anacceleration of 4.49 rad/s2?
N

(b) What force is required if you shift to a 5.70-cm-diametersprocket?
