Two people, each with a mass of 65.0 kg, are on the same carousel. One is standing 3.00 meters from the center, and the other is standing 7.00 meters from the center. If the closer person has an angular momentum of 2,340 kg m²/s, what is the angular momentum of the person standing at 7.00 meters? (Remember: both people have the same angular velocity.)

5,460 kg m²/s

5,920 kg m²/s

12,700 kg m²/s

41,400 kg m²/s

I worked the problem and got 5,460 kg m²/s and it was wrong.
