A uniform rod of mass 3.05×10^-2?2kg and length 0.370m rotates in a horizontal plane about a fixed axis through its center and perpendicular to the rod. Two small rings, each with mass 0.240 kg , are mounted so that they can slide along the rod. They are initially held by catches at positions a distance 4.60×10^-2m on each side from the center of the rod, and the system is rotating at an angular velocity 30.0 rev/min . Without otherwise changing the system, the catches are released, and the rings slide outward along the rod and fly off at the ends.

Part A What is the angular speed of the system at the instant when the rings reach the ends of the rod?

Part B What is the angular speed of the rod after the rings leave it?
