You are driving a 2520.0 kg car at a constant speed of 14.0 m/s along an icy, but straight, level road. As you approach an intersection, the traffic light turns red. You slam on the brakes. Your wheels lock, the tires begin skidding, and the car slides to a halt in a distance of 25.5 m. What is the coefficient of kinetic friction between your tires and the icy road?

solve for a. Then note that a=mu*g
