Acar is safely negotiating an unbanked circular turn at a speed of 25 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 car?
