A track is built so that going around a curve (R = 65.0 m), the banking of the track will allow the automobile to safely travel the curve when there is no friction at a speed of 22.0 m/s. (a) What is the angle of the banking for the curve?  (b) What coefficient of friction is required for the vehicle to travel the same curve with a speed of 34.0 m/s?
