Use the data given in the following table and draw the displacement-time graph for the object :

Using the graph, find the average velocity (i) for first 4s (ii) for next 4s and (iii) for last 6 s.

Explanation

(i) For first 4s, average velocity `= 1 ms ^(-1)`
(ii) For next 4 s, average velocity `=0 ms ^(-1)`
(iii) For last 6s, average velocity `= -1 ms ^(-1)`
