A banked circular highway curve is designed for traffic moving at 62 km/h. The radius of the curve is 214 m. Traffic is moving along the highway at 41 km/h on a rainy day. What is the minimum coefficient of friction between tires and road that will allow cars to take the turn without sliding off the road? (Assume the cars do not have negative lift.)

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 = 0.4, the radius of curvature is 25 m, and the banking angle is 14°, what is the maximum speed at which a car can safely navigate such a turn?
