You are driving a 2500.0-kg car at a constant speed of 14.0 m/s along an icy, but straight and level road. While approaching a traffic light, it 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 25.0 m. What is the coefficient ([tex]\mu[/tex])of sliding friction between your tires and the icy roadbed? W=mg=2500.0(9.8) = 24 500 N Normal force=Fn=W=24 500 N Exerted force = Fa = ma = 2500.0 (-3.92) = -9800 N How do I go on from here?
