A brake drum/wheel assembly on a car has a moment of inertia of 0.42 kgm². When car is traveling at 18m/s a normal force equal to 95N is applied through the brake block on the wheel drum. The coefficient of friction between the brake block and the wheel drum is 0.1. The radius of the wheel is 300mm and the radius of the drum is 175mm. The car has brakes applied to two front wheels and they do not lock (the wheels rotate without skidding during braking). What distance does the car stop in.
