(44 points if you can help me with this physics question)
Sarah stretches her arms out 0.6 m from the center of her body while holding a 2 kg mass in each hand. She then spins around on an ice rink at 1.1 m/s.
What is the combined angular momentum of the masses?
part 2 is:
If she pulls her arms in to 0.15 m, what is her linear speed if the angular momentum remains constant?
