Two trolleys of masses m and 3m are connected by a spring. They are compressed and released, they move off in opposite direction and come to rest after covering distances `s_(1) and s_(2)` respectively. If the frictional force between trolley and surface is same in both the cases then the ratio of distances `s_(1):s_(2)` is

A

`1:9`

B

`1:3`

C

`3:1`

D

`9:1`

Text Solution

Verified by Experts

The correct Answer is:
D
`m_(1)v_(2)=m_(2)v_(2), (s_(1))/(s_(2))=((v_(1))/(v_(2)))^(2)`
