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)

The principle of conservation of momentum states that in the absence of external forces, the total momentum before a collision is equal to the total momentum after the collision. Therefore, the magnitude of the total momentum just after the collision will be equal to the sum of the individual momenta.
Given that the returner's momentum is 0 kg-m/s and the diving player's momentum is 130 kg-m/s, the total momentum just after the collision will be 130 kg-m/s.
So the correct answer is 130 kg-m/s.
