Homework Help: Physics

Posted by please help on Monday, November 26, 2012 at 3:09pm.

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 1750-kg automobile traveling at 28 m/s comes to a halt, how much does the temperature rise in each of the four 8.0 kg iron brake drums? (The specific heat of iron is 448 J/kg C.)
