Friction between the brake drums and the brake shoes, Physics

When a driver brakes an automobile, the friction between the brake drums and the brake shoes converts the car's kinetic energy to thermal energy. If a 1800 kg automobile traveling at 36 m/s comes to a halt, how much does the temperature rise in each of the four8.0 kg iron brake drums? (The specific heat of iron is 448J/kg°C.)
