If a car takes a banked curve at less than the ideal speed, friction is needed to keep it from sliding toward the inside of the curve (a real problem on icy mountain roads). a) Calculate the ideal speed, in km/h, to take a 140 m radius curve banked at 18.0°. b) What is the minimum coefficient of friction needed for a frightened driver to take the same curve at 25.0 km/h?
