Engineers who design roads typically “bank” (incline) curves in such a way that a car traveling at the recommended speed does not have to rely on friction between its tires and the road in order to round the curve. Suppose the radius of curvature of a road segment is 50 m, and the recommended speed is 40 km/hr. At what angle should the curve be banked?
