The acceleration of a particle starting ...

The acceleration of a particle starting from rest and travelling along a straight line is shown in figure. The maximum speed of the particle is

A

`20 ms^-1`

B

`30 ms^-1`

C

`40 ms^-1`

D

`60 ms^-1`

Text Solution

Verified by Experts

The correct Answer is:
B
Maximum speed is at `t = 8 sec`
`v` at `t = 8 sec` is given by are under curve `OABC`.
Max. speed `= (1)/(2)(AB + OC) xx BC`
=`(1)/(2) xx (12) xx 5 = 30 ms^-1`.
