2. From the table given, plot a displacement-time graph.

td>12

Time(s)	0	1	2	3	4	6	8	10
Displacement(m)	3	6	9	12	12	6	0

From the graph

Given tabular data

To find displacement at (i)5s (ii)7s and (iii)9s

Average velocity between (i) 0-3s (ii) 3 -6 s(iii)6-10s

Solution:

Plotting given tabular data we get the following graph

From the graph

the displacements are as follows

(i) at 5s; 12 m

(ii) at 7s; 9 m

(iii)at 9s; 3m

Average velocity between

(i) 0 and 3 s;      average velocity = $\frac{12-3}{3-0}= 3$ $ ms^-1$

(ii) 3 and 6s; average velocity = $\frac{12-12}{6-3}= 0$ $ ms^-1$

(iii) 6 and 10s; average velocity=$\frac{0-`12}{10-6}= -3$ $ ms^-1$
