Figure 2.14 gives the x-t plot of a particle in one-dimensional motion. Three different equal intervals of time are shown. In which interval is the average speed greatest, and in which is it the least? Give the sign of average velocity for each interval.
Step-by-Step Verified Solution
**Answer:** Average speed is greatest in interval 3 and least in interval 2. Average velocity is positive in intervals 1 and 3, negative in interval 2.
**Step-by-Step Explanation:**
Average speed = |_x|/_t. From the graph, interval 3 has the largest |_x| and interval 2 has the smallest |_x|. Average velocity = _x/_t. Interval 1 and 3 have positive _x, interval 2 has negative _x.
