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

`20ms^(-1)`

B

`30ms^(-1)`

C

`40ms^(-1)`

D

`60ms^(-1)`

Text Solution

Verified by Experts

The correct Answer is:
B
b. Maximum speed is at t = 8 s
v at t = 8 s is given by area under curve OABC.

Maximum speed
`= 1/2 (AB+OC)xxBC = 1/2 xx (12) xx 5 = 30 ms^(-1)`.
