## Question:

What is the maximum speed at which a car can round a curve of 25-m radius on a level road if the coefficient of static friction between the tires and road is 0.80?

## Centripetal Force:

Centripetal Force is a force pulling us toward the center of a curve when we travel on a circular path. Other forces and help to offset this force, such as friction. By knowing the frictional conditions of a roadway, we can determine the maximum safe speed of travel.

To find the maximum speed of the car, we must find the slip-point: the speed at which the centripetal force and the force of friction are the same.
