The diagram below shows a speed-time graph for a low-friction cart that was moving along four segments of track. For this situation, you can ignore the effects of friction. The graph consists of four straight-line segments labeled I through IV. During which segment(s), if any, does the graph provide evidence that there is a force being applied to the cart in the opposite direction to its motion? I only II only III and IV I, III and IV All four segments The diagram below shows a speed-time graph for a low-friction cart that was moving along four segments of track.
