Question
![(II) A uniform disk turns at 3.3 rev/s around a frictionless
central axis. A nonrotating rod, of the same mass as the disk
and length equal to the disk's
diameter, is dropped onto the
freely spinning disk, Fig. 8–56.
They then turn together around
the axis with their centers
superposed. What is the angular
frequency in rev/s of the
combination?
