A hockey puck with a mass of 0.16 kg travels at a velocity of 40 m/s toward a goalkeeper. The goalkeeper has a mass of 120 kg and is at rest. Assuming a closed system, find the total momentum of the goalkeeper and puck after the puck is caught by the goalkeeper. In 3-4 sentences, identify the object with the greater momentum after the puck is caught and explain your reasoning.(4 points)

Answer 1

The goalie and the puck join together after the goalie catches the puck. The total momentum of the goalie and the puck would be the same as the momentum of the puck before it was caught. The greater momentum would be the puck because it was moving really fast before the goalie caught it.
