A mass m moves with a velocity v and collides with another identical mass. After collision, the first mass moves with velocity `v//sqrt(3)` in a direction perpendicular to the initial direction of motion. Find the speed of the second mass after collision.

A

v

B

`sqrt3 v`

C

`(2)/(sqrt3) v`

D

`(v)/(sqer3)`

Text Solution

Verified by Experts

The correct Answer is:
C

From COLM
`mv_(2) = sqrt((mv^(2)) + (m (v)/(sqrt3))^(2)) rArr v_(2) = (2v)/(sqrt3)`
