Problem
Two uniform solid disks rotate about identical fixed central axes with the same angular speed ω. Disk A has moment of inertia I, whereas Disk B has moment of inertia 3I. Without detailed calculation, identify which disk has the greater rotational kinetic energy and state the factor by which it differs from the other.
