Auniform solid sphere with mass m and radius r is rotating about an axis which is a distance of 2r from the center of the sphere. calculate the moment of inertia of the system (kg. m2) if m=2kg and r=1m. (moment of inertia of a solid sphere rotating about its center of mass = 2/5 mr2)

do you have a formula possibly

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.
