PART 11: Explain the following problems? COMM: 10 1. You pull a box with a constant force across a frictionless table using an attached rope held horizontally. If you now pull the rope with the same force but at an angle above the horizontal (with the box remaining on table), does the acceleration increase. Decrease, or remain the same? Explain.
