    What's your problem? Does this have to do with the conservation of momentum?

    Conservation of Momentum. Initial momentum must equal final momentum. Therefore...

    (mass)x(velocity) = (mass)x(velocity)


    (massA)x(velocityA) + (massB)x(velocityB) ... (massX)x(velocityX) =
    (massA)x(velocityA) + (massB)x(velocityB) ... (massX)x(velocityX)
