# Math Help - Rolling Friction

1. ## Rolling Friction

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
