Question

6. If the circular track were to suddenly become frictionless at the instant shown in the diagram, the car's direction of travel would be (1 point) (1) toward E (2) toward N (3) toward W (4) a clockwise spiral 7. At the instant shown in the diagram, the car's centripetal acceleration is directed (1 point) (1) toward E (2) toward N (3) toward W (4) clockwise 8. Which factor, when doubled, would produce the greatest change in the centripetal force acting on the car? (1 point) (1) mass of the car (2) radius of the track (3) velocity of the car (4) weight of the car
