The coefficient of sliding friction between rubber tires and wet pavement is 0.50. The
brakes are applied to a 750 kg car traveling 30 m per second, and the car skids to a stop.
What is the magnitude and direction of the force of friction that the road exerts on the car?
What would be the magnitude and direction of the acceleration of the car? Why would it be
constant? How far would the car travel before stopping?
