 P: 3 how can you tell if the frictional force is great enough to keep a car turning a curb in circular motion based on the coefficient of friction and the normal force?
 HW Helper Sci Advisor Thanks P: 7,850 If a vehicle of mass m turns a corner radius r at speed v, what is its acceleration? What force is needed to provide that acceleration? Where will that force come from?
 P: 3 Acceleration: 0.173 m/s/s Force is coming from engine but the street is wet with oil.

## Normal and Friction Force Relationships went turning curbs

A car with a velocity of 15.3 m/s follows a circular road that has a radius of 40 m. The car has a mass 1350 kg. The pavement is wet and oily so the coefficient o friction between the tires and the road is only .500. The frictionall force that I calculated came out to be 6620 Newtons. Is this frictional force large enough to maintain the car in circular motion?
