A car with a mass of 1200 kg, traveling at 60 ft/sec, brakes to a stop within 40 ft. Assume that the braking force is constant during that phase. A truck, 20 times as heavy as the car, is employing the same braking force. What will be the truck's stopping distance when traveling at the same speed? If the truck needs to stop also within 40 ft, what statement can you make about the energy dissipation by the brakes? How can you figure the temperature rise by the brakes? Provide your explanation using the principle of work and energy.
