A 972 kg car is going 20 ms and the driver has to slam on, Ask an Expert

Academics

A 972 kg car is going 20 m/s and the driver has to slam on his brakes to prevent an accident. Assume that a total of 23.2 kg of iron in the brake pads and rotors absorb the heat produced by the friction between the brake pads and rotors. After the car has stopped, what is the change in temperature of the brake pads and rotors.
