Question
A uniform, 0.0350 kg rod of length 0.350 m rotates in a horizontal
plane about a fixed axis through its center and perpendicular to the
rod. Two small rings, each with mass 0.0150 kg, are mounted so that
they can slide without friction along the rod. They are initially held by
catches at positions 0.0550 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.
