A starts from rest and moves with acceleration `a_(1)`. Two seconds later B starts from rest and moves with an acceleration `a_(2)`. If the displacement of A in the `5^(th)` second is the same as that of B in the same interval, the ratio of `a_(1)` to `a_(2)` is

A

`9:5`

B

`5:9`

C

`1:1`

D

`1:3`

Text Solution

Verified by Experts

The correct Answer is:
B
`s_(1) = (a)/(2)(2n-1), s_(2) = (a)/(2)(2n-1)`
Accoridng to given prob. `S_(1) = S_(2)`
