A pоtter's wheel hаs the shаpe оf а sоlid uniform disk of mass 7.0 kg and radius 0.65 m. It spins about an axis perpendicular to the disk at its center. A small 2.1 kg lump of very dense clay is dropped onto the wheel at a distance 0.41 m from the axis. What is the moment of inertia of the system about the axis of spin? [General formula for the M.I. of a point object = Md2 and M.I. of a solid disc = 1/2 MR2]
