A body of mass ${m_1}$is moving with a velocity $V$. It collides with another stationary body of mass ${m_2}.$ They get embedded. At the point of collision, the velocity of the system
By momentum conservation before and after collision.
${m_1}V + {m_2} \times 0 = ({m_1} + {m_2})v$ ==> $v = \frac{{{m_1}}}{{{m_1} + {m_2}}}V$
i.e. Velocity of system is less than $V.$
