A bullet of mass `'x'` moves with a velocity `y`, hits a wooden block of mass `z` at rest and gets embedded in it. After collision, the wooden block and bullet moves with a velocity

A

`(x)/(x+z)y`

B

`(x+y)/(x)y`

C

`(z)/(x+y)y`

D

`(x+y)/(z)y`

Text Solution

Verified by Experts

The correct Answer is:
A
`vec(v) = (m_(1)vec(u_(1))+m_(2)vec(u_(2)))/(m_(1)+m_(2))`
