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