Car Tire Skidding: Deceleration with uk = 0.8

[physics_10]

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?

I'm not sure how I am supposed to solve this if only the uk is provided?

Use Newton's 2nd law.
