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)

Answer 1

To determine the total momentum just after the collision, we can use the principle of conservation of momentum. The total momentum before the collision equals the total momentum after the collision.

Before the collision:

• The returner's momentum = 0 kg-m/s
• The opposing player's momentum = 130 kg-m/s

Total momentum before the collision = momentum of returner + momentum of opposing player Total momentum before the collision = 0 kg-m/s + 130 kg-m/s = 130 kg-m/s

Since no external forces are acting on the system during the collision, the total momentum after the collision will also be 130 kg-m/s.

Therefore, the magnitude of the total momentum just after the collision will be:

130 kg-m/s.

So the correct answer is 130 kg-m/s.
