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.
The total momentum of the system can be found by using the principle of conservation of momentum, which states that the total momentum before an event is equal to the total momentum after the event in a closed system. Since the goalkeeper is at rest initially, the total momentum before the puck is caught is equal to the momentum of the puck, which is given by the product of its mass and velocity. Therefore, the total momentum after the puck is caught by the goalkeeper will be equal to the momentum of the puck alone. Thus, the puck will have greater momentum after being caught by the goalkeeper.
