The acceleration-time graph of a particle moving in a straight line is as shown in figure. The velocity of the particle at time `t = 0` is `2 m//s`. The velocity after `2` seconds will be

A

`6m//s`

B

`4m//s`

C

`2m//s`

D

`8m//s`

Text Solution

Verified by Experts

The correct Answer is:
A
`v(2)=v(0)+` area under `a-t` graph from `t=0` to `t=2`
`=2+(1)/(2)(2)(4)=6m//s`
