When a car goes around a circular curve on a level road,

a. no frictional force is needed because the car simply follows the road.

b. the frictional force of the road on the car increases when the car's speed decreases.

c. the frictional force of the road on the car increases when the car's speed increases.

d. the frictional force of the road on the car increases when the car moves to the outside of the curve.

e. there is no net frictional force because the road and the car exert equal and opposite forces on each other?

The correct answer would be C. When a car moves around a circular curve, the frictional force of the road on the car increases as the speed of the car increases. velocity and the friction force would be directly proportional so that as the speed increases the force would increase as well.
