Application of Circular Motion

Example 3

A 1200 kg car rounds a corner of radius r = 45 m. If the coefficient of static friction between the tires and the road is , what is the greatest speed the car can have in the corner without skidding?

Solution

 

Example 4

The figure represents a stock car of mass m = 1600 kg traveling at a constant speed v = 20 m/s around a flat, circular track of radius R = 190 m. For what value of between the track and the tires of the car will the car be on the verge of sliding off the track?
