A car is safely negotiating an unbanked circular turn at a speed of 18 m/s. The road is dry, and the maximum static frictional force acts on the tires. Suddenly a long wet patch in the road decreases the maximum static frictional force to one third of its dry-road value. If the car is to continue safely around the curve, to what speed must the dirver slow the car?

A car is safely negotiating an unbanked circular turn at a speed of 29 m/s. The road is dry, and the maximum static frictional force acts on the tires. Suddenly a long wet patch in the road decreases the maximum static frictional force to one-sixth of its dry-road value. If the car is to continue safely around the curve, to what speed must the driver slow the car? m/s

Two curves on a highway have the same radii. However, one is
unbanked and the other is banked at an angle of degrees. A car can safely travel along the
unbanked curve at a maximum speed under conditions when the coefficient of
static friction between the tures and the road is . The banked curve is frictionless, and the
car can negotiate it at the same maximum speed . Find the coefficient of static friction
between the tires and the...

Concept Simulation 5.2 reviews the concepts that are involved in this problem. A car is safely negotiating an unbanked circular turn at a speed of 23 m/s. The road is dry, and the maximum static frictional force acts on the tires. Suddenly a long wet patch in the road decreases the maximum static frictional force to one third of its dry-road value. If the car is to continue safely around the curve, to what speed must the driver slow the...
