Suppose you are on a cart initially at rest that rides on a frictionless track. If you throw a ball off the cart towards the left, will the cart be put into motion? 0% ac e. th e pl le gh t. ri ai n ,t o N o, i tw ill re m Ye s th e ,t o Ye s 0% ft . 0% in A. Yes, to the right. B. Yes, to the left. C. No, it will remain in place. Suppose you are on a cart that is moving at a constant speed v to the left on a frictionless track. If you throw a massive ball straight up (from your perspective), how will the speed of the cart change?
