A particle of mass 2m moving with velocity v strikes a stationary particle of mass 3m and sticks to it. The speed of the system will be

A

`v//2`

B

2v

C

`v//3`

D

3v

Text Solution

Verified by Experts

The correct Answer is:
C

Initial momentum = mv
Final momentum = 3mV
By the law of conservation of momentum mv= 2mV
`therefore V= v//3`
