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

A

3v

B

v/3

C

2v

D

v/2

Text Solution

Verified by Experts

The correct Answer is:
B

Let v be the velocity of system ,
the momentum will conserved
` mv + 2m(0)=(m+2m)v.`
`mv = 3mv.`
`v. = v/3 `
