He driver of an 1800 kg car (including passengers) traveling at 23.0 m/s slams on the brakes, locking the wheels on the dry pavement. The coefficient of kinetic friction between rubber and dry concrete is typically 0.700. a) Use the work - energy p rinciple to calculate how far the car will travel before stopping. B) How far would the car travel if it were going twice as fast? C) What happened to the car’s original kinetic energy
