A sphere of solid aluminum (r = 2.7 g/cm3 ) has a radius R, a mass M, and a moment of inertia I0 about its center. A second sphere of solid aluminum has a different mass M’ with a radius 2R. What is the moment of inertia of the second sphere about its center I in terms of the first sphere I0? Mass should not appear in your answer (4 points).
