A car of mass 1500 kg is moving on a horizontal and straight road at 20 m/s. At some point the driver hits the brakes and the car comes to a stop after it had moved a distance of 36m while the brakes were on. What is the coefficient of the kinetic friction between the wheels of the car and the road?

A 2300 kg car moving at an initial speed of 25 m/s along a horizontal road skids to a stop in 50 m. (Note: When stopping without skidding and using conventional brakes, 100 percent of the kinetic energy is dissipated by friction within the brakes. With regenerative braking, such as that used in hybrid vehicles, only 70 percent of the kinetic energy is dissipated.) (a) Find the energy dissipated by friction. 718750 Incorrect: Your answer is incorrect. kJ (b) Find...

Traveling at 40.2 m/s, a driver applies the brakes to his fast-moving car and skids out of control on a wet concrete horizontal road. The 2000 kg car is headed directly toward a student waiting to catch a bus to campus who is standing 58.0 m down the road. Luckily, Superman is flying overhead and surveys the situation. Knowing that the coefficient of kinetic friction between rubber and rough wet concrete is .800, he determines that friction alone will not...
