Step-by-step explanation:
The maximum change happens when all 500 people moves form outer surface to the station center. When all of them are at the surface, the total moment of inertia is:
When they are at the axis, the total moment of inertia is only the station's, which is
By the law of angular momentum conservation:
So the angular speed changes by 0.08 of itself, or 8%
