प्रश्न
A body is moving in a straight line and its displacement at various instants of time is given in the following table
| Time (s) | 0 | 1 | 2 | 3 | 4 | 5 | 6 | 7 |
| Displacement (m) | 2 | 6 | 12 | 12 | 12 | 18 | 22 | 24 |
Plot the displacement-time graph and calculate
(i) Total distance travelled in the interval 1 s to 5 s.
(ii) Average velocity in time interval 1 s to 5 s.

उत्तर
(i) Total distance travelled in interval 1s to 5s = 18m - 6m = 12 m.
(ii) Average velocity = Total displacement in the given time interval/Time interval, i.e. 1 s to 5 s.
Or, Average velocity = 12 m/4 s = 3 m/s.
