    This is a problem related to momentum and its conservation.

    Momentum(p)= Mass * Velocity and in a closed system it is conserved i.e. Initial momentum=Final momentum.

    Now for our case, since ...

    Solution Summary

    Momentum(p)= Mass * Velocity and in a closed system it is conserved i.e. Initial momentum=Final momentum.
