Question
A uniform, 0.0300 kg rod of length 0.400 m rotates in a
horizontal plane about a fixed axis through its center and perpendicular
to the rod. Two small rings, each with mass 0.0200 kg, are mounted so
that they can slide without friction along the rod. They are initially held
by catches at positions 0.0500 m on each side of the center of the rod,
and the system is rotating at 48.0 rev/min. With no other changes in the
system, the catches are released, and the rings slide outward along the
rod and fly off at the ends. What is the angular speed (a) of the system
at the instant when the rings reach the ends of the rod; (b) of the rod
after the rings leave it?
