A football kick returner catches the ball just as a player from the opposing team dives to tackle him. At the time of impact, the returner’s momentum is 0 kg-m/s, and the diving player’s momentum is 130 kg-m/s. What will the magnitude of the total momentum be just after the collision?(1 point) Responses 260 kg-m/s 260 kg-m/s 0 kg-m/s 0 kg-m/s 65 kg-m/s 65 kg-m/s 130 kg-m/s
The law of conservation of momentum states that the total momentum before a collision is equal to the total momentum after the collision. Since the returner's momentum is 0 kg-m/s and the diving player's momentum is 130 kg-m/s, the total momentum before the collision is 0 + 130 = 130 kg-m/s. Therefore, the magnitude of the total momentum just after the collision will also be 130 kg-m/s.
So the correct answer is 130 kg-m/s.
