Consider again the problem of a car traveling along a banked turn. Sometimes roads have a "reversed" banking angle. That is, the road is tilted "away" from the center of curvature of the road. If the coefficient of static friction between the tires and the road is μs = 0.6, the radius of curvature is 18 m, and the banking angle is 12°, what is the maximum speed at which a car can safely navigate such a turn?
An 860 kilogram race car can drive around an unbanked turn at a maximum speed of 59 meter per second without slipping. Compute the maximum speed if no down force acted on car
