3. Jessica 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.

a. What is the combined angular momentum of the masses?

b. If she pulls her arms in to 0.15 m, what is her linear speed if the angular momentum remains constant?
