| A particle starts from the origin at time\[t=0\]and moves along the positive x-axis. The graph of velocity with respect to time is shown in figure. What is the position of the particle at time\[t=5s\]? |
 |
A) \[10m\]
B) \[6m\]
C) \[3m\]
D) \[9m\]
Correct Answer: D
Solution :
| \[{{r}_{t=5}}=area\] |
| \[=\left( \frac{1}{2}\times 2\times 2+2\times 2+3\times 1 \right)m\] |
| \[=(2+4+3)m=9m\] |
