A particle of mass ``m`` moving with velocity v strikes a particle of mass ``2m`` at rest and sticks to it. The speed of the combined mass is

A

`v/2`

B

2v

C

`v/3`

D

`v/4`

Text Solution

Verified by Experts

The correct Answer is:
C
According to conservation of linear momentum
`mv=(m+2m)v^(1)`
`v_(1)(mv)/(3m)=v/3`
