You are driving a 2570.0kg car at a constant speed of 14.0 m/s along a wet, but straight, level road. As you approach an intersection, the traffic light turns red. You slam on the brakes. The car's wheels lock, the tires begin skidding, and the car slides to a halt in a distance of 24.6 m. What is the coefficient of kinetic friction between your tires and the wet road?

Physics 
drwls,
Friction work = initial kinetic energy
M*g*mu*X = (1/2)M*V^2
M cancels out. Solve for mu, the coefficient of friction
