you notice another ant beginning to walk along a meter stick. curious, you take out a stopwatch and determine the ant’s position on the meter stick. you record the following data: {(0.0 s, 0.0 m), (1.0 s, 0.12 m), (2.0 s, 0.24 m), (3.0 s, 0.36 m), (4.0 s, 0.48 m)}. determine the ant’s speed from the slope of the distance vs. time graph.
