A 320-kg car is moving at 25.0 m/s. Suddenly after the breaks are hit to lock the wheels, it comes to a screeching stop in an 8.0-m distance.
A.) Calculate the change in kinetic energy of the car when it comes to a stop.
B.) What is the combined work done by the road friction and air drag during the car's deceleration?
C.) Calculate the average value of the combined force due to the road friction and the air drag on the car.
