A Space Station Out Beyond the Solar System Is Rotating

Multiple Choice

A space station out beyond the solar system is rotating with constant angular velocity.

When the spaceship docks, the angular momentum of the system consisting of the station and ship:

A) is less than the original angular momentum of the station.
B) is the same as the original angular momentum of the station.
C) is greater than the original angular momentum of the station.
D) is less than the original angular momentum of the station, but the angular velocity increases.
E) is greater than the original angular momentum of the station, but the angular velocity decreases.
