A `6 kg` mass collides with a body at rest. After the collision, they travel together with a velocity one third the velocity of `6 kg` mass. The mass of the second body is

A

6 kg

B

3 kg

C

12 kg

D

18 kg

Text Solution

Verified by Experts

The correct Answer is:
`(3)`
`m_(1)u_(1) + m_(2)u_(2) = (m_(1) +m_(2))v`
