A car accelerates from rest with acceleration `2 m//s^(2)` on a straight line path and then comes to rest after applying brakes. Total distance travelled by the car `100 m` in 20 seconds. Then, the maximum velocity attained by the car is.

A

`10 m//s`

B

`20 m//s`

C

`15 m//s`

D

`5 m//s`

Text Solution

Verified by Experts

The correct Answer is:
A

`(V_(0))/(t_(0)) = 2` ….(i)
`(1)/(2) xx 20 xx V_(0) = 100`
`V_(0) = 10 m//s`
