(44 points if you can 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?

the body's situation won't change the forces are equal opposit and on the same body

jupiter is the largest planet in our solar system, having a mass and radius that are respectively, 318 and 11.2 times that of earth. suppose that an object falls from rest near the surface of each planet and that the acceleration due to gravity remains constant during the fall. each object falls the same distance before striking the ground. determine the ratio of the time of fall on jupiter to that on earth.
