A car travels at constant speed around a corner. The cars speed is 35 m/s and the radius of the circle is 0.25 km. The coefficient of static friction between the tires and the road is 0.7.
What is the frictional force needed for the car to make the turn?
What is the maximum force the static friction can produce?
Does the car stay on the road?
The car is in motion so why is the static friction important?

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

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?
