Acivil engineer wishes to redesign the curved roadway in the example what is the maximum speed of the car? in such a way that a car will not have to rely on friction to round the curve without skidding. in other words, a car of mass m moving at the designated speed can negotiate the curve even when the road is covered with ice. such a road is usually banked, which means that the roadway is tilted toward the inside of the curve. suppose the designated speed for the road is to be v = 12.2 m/s (27.3 mi/h) and the radius of the curve is r = 38.0 m. at what angle should the curve be banked?
