A car is traveling down a hill that makes an angle of 13° with the horizontal. The driver applies her brakes, and the wheels lock so that the car begins to skid. The coefficient of kinetic friction between the tires and the road is ?K = 0.51.

A) Find the acceleration of the car.

B) How long does the car take to skid to a stop if its initial speed is 29 mph (13 m/s)?
