A particle starting from rest. Its acceleration (a) versus time (t) is as shown in the figure.
The maximum speed of the particle will be.

A

`110 m//s`

B

`55 m//s`

C

`550 m//s`

D

`660 m//s`

Text Solution

Verified by Experts

The correct Answer is:
B
The area under acceleration-time graph gives change in velocity. As acceleration is zero at the end of `11 sec`, we have
`v_(max) = "Area of" Delta OAB`
=`(1)/(2) xx 11 xx 10 = 55 m//s`.
