A mass 'm' moves with a velocity '' and ...

A mass 'm' moves with a velocity '' and collides inelastically with another identical mass. After collision the Ist mass moves with velocity in a direction perpen-dicular to the initial direction of motion Find the speed of the 2nd mass after collision :

A

v

B

`sqrt(3v)`

C

`2(sqrt(3))v`

D

`(v)/(sqrt(3))`

Text Solution

Verified by Experts

The correct Answer is:
c
Applying conservation of momentum `mv=mv_1 cos theta`
COD
`o=(mv)/(sqrt3)-mv_1sin theta`
`:. V_1=(2)/(sqrt3)v`
