A bullet of mass $ a$ and velocity $b$ is fired into a large block of mass $c$. The final velocity of the system is
$\frac{c}{{a + b}} \cdot b$
$\frac{a}{{a + c}} \cdot b$
$\frac{{a + b}}{c}.a$
$\frac{{a + c}}{a} \cdot b$
A bullet of mass $ a$ and velocity $b$ is fired into a large block of mass $c$. The final velocity of the system is
Initially bullet moves with velocity b and after collision bullet get embedded in block and both move together with common velocity.
By the conservation of momentum
$==> a × b + 0 = (a + c) V$ ==> $V = \frac{{ab}}{{a + c}}$
