1 of 3 • A cart is moving along a track to the right with constant speed v. Evidently the net force acting upon the cart is. • rightward. • zero. • leftward. v 2
2 of 3 • A cart is connected to a hanging mass by a rope draped over a pulley. There is no friction (drag) between the cart and the track, nor the rope and the pulley. The cart and hanging mass have equal mass. Once released from rest, the hanging mass will fall with an acceleration of magnitude • zero. • Less than 0.5g but greater than zero. • 0.5g. • Greater than 0.5g but less than g. • g. 3
3 of 3 • A cart is connected to a hanging mass by a rope draped over a pulley. There is no friction (drag) between the cart and the track, nor the rope and the pulley. The cart and hanging mass have equal mass. Once released with the initial velocity shown, the hanging mass will fall with an acceleration of magnitude • zero. • Less than 0.5g but greater than zero. • 0.5g. • Greater than 0.5g but less than g. • g. v v 4
