Lightning McQueen goes around a corner which is banked (inclined downwards towards the center of the radius of curvature). The centripetal force that causes Lightning McQueen to go round a bend in the road is usually provided by friction. This road is very icy, however. Could the force required to turn the corner be provided if the friction coefficient between the car’s tires and the road goes to zero?

Find the velocity required by the car if the radius of curvature of the curve is 100 m and the road is banked at 20 ^o to the horizontal.
