Question

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`

Answer 1

Correct Answer - A

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