As the car goes around the curve, the centripetal force is directed--

• toward the center of the circular curve

• away from the center of the circular curve

• tangent to the curve in the direction of motion

• tangent to the curve opposite the direction of motion

• It keeps going in a circular path until friction stops it

• It flies off in a straight line until it hits something

• It immediately stops moving
