A bullet of mass `m` and velocity `v` is fired into a large block of mass `M`. The final velocity of the system is

A

`c/(a+b) b`

B

`a/(a+c) b`

C

`(a+b)/c a`

D

`(a+c)/a.b`

Text Solution

Verified by Experts

The correct Answer is:
B
From momentum conservation `P_(i)=P_(f)`
ab=(a+c)v
`v=(ab)/(a+c)`
