Stopping at a red light: A 1500 kg car at a constant speed of 10 m/s is driving along a wet, but straight , level road. As the car approaches an intersection, the traffic light turns red. The driver of the car slam on the brakes. The car's wheels lock, the tires begin skidding, and the car slides to a halt in a distance of 25 m. a). Draw a sketch of the scenario. b) What is the momentum of the car, before the brakes were applied? c). What is the average force of the brakes in stopping the car? d) What is the normal force on the car? e). What is the coefficient of kinetic friction between the tires and the wet road?
