A 1200-kg car is initially traveling at 80 km/h when the driver spots a large boulder in the road. The driver slams on the brakes, the wheels lock, and the car slides to a stop in 3.8 seconds. a. Show the forces that act on the car on the diagram below. b. Calculate the constant deceleration of the car. C. How far will the car slide before coming to a complete stop? d. Using the work-energy principle, calculate the net work done by the friction force on the car. e. Calculate both the friction force and the coefficient of friction for this situation.
