    here we have to apply the total momentu conservation law. So we can write this: \[\Large {m_1}{v_1} + {m_2}{v_2} = \left( {{m_1} + {m_2}} \right)V\]

    where V is the requested speed: \[\Large V = \frac{{{m_1}{v_1} + {m_2}{v_2}}}{{{m_1} + {m_2}}} = \frac{{0.4 \times 2 + 1.2 \times 0}}{{0.4 + 1.2}} = ...m/\sec \]

    so we get 0.5? so choice A is our solution?
