The combined mass of the motorcycle and rider is 160 kg. Each 9-kg wheel has a 330-mm radius and a moment of inertia I = 0 8 kg-m2. The engine drives the rear wheel by exerting a couple on it. If 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 and (b) the normal forces exerted on the road by the rear and front wheels. (The location of the center of mass of the motorcycle, not including its wheels, is shown.)
