The radius of curvature of a highway exit is r 955 m the, Ask an Expert

Academics

The radius of curvature of a highway exit is r = 95.5 m. The surface of the exit road is horizontal, not banked. (See figure.)

If the static friction between the tires and the surface of the road is μs = 0.408, then what is the maximum speed at which the car can exit the highway safely without sliding?
