When a driver brakes an automobile, friction between the brake disks and
the brake pads converts part of the car's kinetic energy to internal energy. If
a 1500 kg automobile traveling at 32 m/s comes to a halt after its brakes
are applied, how much can the temperature rise in each of the four 3.5
kg steel brake disks? Assume the disks are made of iron (c = 448 J/kg•°C)
and that all of the kinetic energy is distributed in equal parts to the internal
energy of the brakes.
