    Rolling Friction

    Can someone please help me with this problem? I have no idea what to do. Thanks

    Mitch is being chase by the cops. He is driving a car of mass 2000 kg at 12 m/s. He turns a corner at an intersection. The radius of his path is 20 m. What does the cofficient of static friction have to be so that he will make the turn w/o sliding?

    Well I drew a free body diagram and got Fn - w = mg for Fy

    F_c = \frac{mv^2}{r} = f_s \le \mu_s \cdot N<br />
