The diagram below shows a speed-time graph for a low-friction cart that was moving alon segments of track. For this situation assume the effects of friction are so small that you ca ignore them. The graph consists of four straight-line segments labeled I through IV. Along segment the cart was either involved in a single interaction or was not involved in any interaction. During which segment(s) does the graph provide evidence that the cart was involved in an interaction? Speed versus Time 120 100 II 80 60 IV 05 1.0 1.5 Time (s) 2.0 2.5 Speed (emi
