# Centripetal force: Car taking an un banked circular turn

Not what you're looking for?

Car taking an un-banked circular turn:

A car is safely negotiating an un-banked circular turn at a speed of 21m/s. The max static frictional force acts on the tires. Suddenly a wet patch in the road reduces the maximum static frictional force by a factor of three. If the car is to continue safely around the curve, to what speed must the driver slow the car?

##### Solution Summary

Solution is provided and well presented. A diagram is used to illustrate the forces on the car. Physics concepts that affect the car's motion are clearly stated.
