Rotational Inertia of a Disk and Point Mass
A small point mass m is attached to the edge of a uniform circular disk of mass M and radius R. The system rotates about an axis perpendicular to the disk that passes through a point on the edge opposite the mass m. What is the total rotational inertia of the system?
A
MR² + mR²
B
MR²/2 + mR²
C
5MR²/4 + 4mR²
D
3MR²/2 + 4mR²
