Answer:
12:B 13: 5 m/s 14: 5 m/s
Explanation:
12: this is a position vs time graph, and that worded description matches the graph because the slope of a p vs t graph is the velocity
13: again, the slope of a position vs time graph is the velocity. 10m/2s = 5 meters a second or m/s
14: same thing. the object travels 30 m in 6 s so 30/6=5 m/s
