The combined mass of the motorcycle and rider is 160 kg. Each 9 kg wheel has a 330 nun radius and mass moment of inertia 1 = 0.8 kg.m2 The engine drives the rear wheel. Lf the rear wheel exerts a 400 N horizontal force on the road and you do not neglect the horizontal force exerted on the road by the front wheel, determine

(a) The motorcycle's acceleration;

(b) The normal forces exerted on the road by the rear and front wheels. (The location of the centre of mass of the motorcycle not including its wheels is shown.)

Strategy: Isolate the wheels and draw three free-body diagrams. The motorcycle's engine drives the rear wheel by exerting a couple on it.
