A motorcycle accelerates from rest, and both the front and rear tires roll without slipping.

(a) Is the force exerted by the ground on the rear tire in the forward or in the backward direction? Explain.

(b) Is the force exerted by the ground on the front tire in the forward or in the backward direction? Explain.

(c) If the moment of inertia of the front tire is increased, will the motorcycle's acceleration increase, decrease, or stay the same? Explain.
