प्रश्न
Using the following data, draw time - displacement graph for a moving object:
| Time (s) | 0 | 2 | 4 | 6 | 8 | 10 | 12 | 14 | 16 |
| Displacement (m) | 0 | 2 | 4 | 4 | 4 | 6 | 4 | 2 | 0 |
Use this graph to find average velocity for the first 4 s, for the next 4 s and for the last 6 s.

उत्तर
From the given data, the displacement-time graph is shown as
Average velocity = `("Change in displacement")/("time interval")`
∴ For first 4s, v1 = `(4 - 0)/4`
= 1 ms−1
For next 4s v2 = `(4 - 4)/4`
= 0 ms−1
For last 6s v3 = `(0 - 6)/6`
= −1 ms−1
