An object is formed by attaching a uniform, thin rod with a mass of mr = 6.85 kg and length l = 5.76 m to a uniform sphere with mass ms = 34.25 kg and radius r = 1.44 m. note ms = 5mr and l = 4r. 1) what is the moment of inertia of the object about an axis at the left end of the rod?
kg-m2
2) if the object is fixed at the left end of the rod, what is the angular acceleration if a force f = 460 n is exerted perpendicular to the rod at the center of the rod?
rad/s2
3) what is the moment of inertia of the object about an axis at the center of mass of the object? (note: the center of mass can be calculated to be located at a point halfway between the center of the sphere and the left edge of the sphere.)
kg-m2
4) if the object is fixed at the center of mass, what is the angular acceleration if a force f = 460 n is exerted parallel to the rod at the end of rod?
rad/s2
5) what is the moment of inertia of the object about an axis at the right edge of the sphere?
