A 2400 kg car moving at an initial speed of 20 m/s along a horizontal road skids to a stop in 66 m. (Note: When stopping without skidding and using conventional brakes, 100 percent of the kinetic energy is dissipated by friction within the brakes. By regenerative braking, such as that used in hybrid vehicles, only 70 percent of the kinetic energy is dissipated.)

1. Discover the energy dissipated by friction.

2. Discover the coefficient of kinetic friction between the tires and the road.
