In Braking an Automobile, the Friction Between the Brake Drums $\degree$

Short Answer

In braking an automobile, the friction between the brake drums and brake shoes converts the car's kinetic energy into heat. If a 1500-kg automobile travelling at 30 m/s brakes to a halt, how much does the temperature rise in each of the four 8.0-kg brake drums? (The specific heat of each iron brake drum is 448 J/kg. $\degree$ C).
