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?
Since momentum is conserved in a collision, the total momentum after the collision will be the sum of the initial momenta of the kick returner and the diving player.
Total momentum after the collision = kick returner's momentum + diving player's 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.
