A particles starts from rest. Its acceleration (a) versus time (t) is as shown in 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
`a=-10/11t+10` at maximum speed `a=0`
`10/11t+10`
`rArr t=11` sec
Area under the curve`=1/2 xx11xx10=55`
