Each year at a college, there is a tradition of having a hoop rolling competition. Alex rolls his 0.25 kg hoop down the course. If the hoop has a radius of 0.5 m, what is the moment of inertia of Alex's rolling hoop?
A particular planet has a moment of inertia of 9.74 * 1037 kg•m2 and a mass of 5.98 * 1024 kg. Based on these values, what is the planet's radius?
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.
What is the combined angular momentum of the masses? If she pulls her arms into 0.15 m, what is her linear speed if the angular momentum remains constant?
