Question

Physics

An object is formed by attaching a uniform, thin rod with a massof mr = 7.04 kg and length L = 5.16 m to a uniform sphere with massms = 35.2 kg and radius R = 1.29 m. Note ms = 5mr and L = 4R.

1)What is the moment of inertia of the object about an axis atthe left end of the rod?

2) If the object is fixed at the left end of the rod, what isthe angular acceleration if a force F = 418 N is exertedperpendicular to the rod at the center of the rod?

3) What is the moment of inertia of the object about an axis atthe center of mass of the object? (Note: the center of mass can becalculated to be located at a point halfway between the center ofthe sphere and the left edge of the sphere.)

4) If the object is fixed at the center of mass, what is theangular acceleration if a force F = 418 N is exerted parallel tothe rod at the end of rod?

5) What is the moment of inertia of the object about an axis atthe right edge of the sphere?
