4. A cyclist is pedaling around a circular level track of radius 45m. The coefficient of static friction between the tires and track is 0.48 and the coefficient of kinetic friction is 0.45. (a) What is the maximum speed of the cyclist without the tires slipping? (b) At this speed, the cyclist suddenly brakes, locking the wheels, and slides to a halt. How far do they slide and in what direction?
