Suppose that the coefficient of kinetic friction of the rubber of a car tire and the street is Uk = 0.8. What is the deceleration of the car on a flat street if the driver brakes sharply, so all the wheels are locked and skidding?

A commuter backs her car out of her garage with a constant acceleration of 1.40 m/s2. (a) How long does it take her to reach a speed of 1.60 m/s? s (b) If she then brakes to a stop in 0.8 s, what is her (constant) deceleration? m/s2
