Question
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 total momentum of a system is conserved in the absence of external forces.
In this situation:
- The momentum of the kick returner before the collision is 0 kg-m/s.
- The momentum of the diving player is 130 kg-m/s.
To find the total momentum just after the collision, we add the momenta of both players at the moment before the collision:
Total momentum = momentum of returner + momentum of diving player
Total momentum = 0 kg-m/s + 130 kg-m/s = 130 kg-m/s
Therefore, the magnitude of the total momentum just after the collision will be **130 kg-m/s**.
In this situation:
- The momentum of the kick returner before the collision is 0 kg-m/s.
- The momentum of the diving player is 130 kg-m/s.
To find the total momentum just after the collision, we add the momenta of both players at the moment before the collision:
Total momentum = momentum of returner + momentum of diving player
Total momentum = 0 kg-m/s + 130 kg-m/s = 130 kg-m/s
Therefore, the magnitude of the total momentum just after the collision will be **130 kg-m/s**.
