For the next four questions, consider the cart on a frictionless track, shown below. For each question, one or more features of the setup have been changed. Assume that there is no friction. You are to indicate what effect the change will have on the acceleration compared to the original setup, which is shown below. (1st picture is the original setup) (2nd picture is the diagram for question 3) 1. What happens to the acceleration if the mass of the cart is increased to 14kg, but the towing force remains the same? A. The acceleration will be greater than the original setup. B. The acceleration will be less than the original setup. C. The acceleration remains the same. D. It's not possible to tell.
