When the two pucks collide, momentum will still be same but it acts in two different directions. Momentum formula goes like this M = m x v, m is mass and v is speed. That means velocity is inversely proportional to mass. So the puck with less weight changes the most, so the 0.156 kg puck changes velocity the most.
