A uniform rod of mass 2.85×10-2kg 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 0.230kg , are mounted so that they can slide along the rod. They are initially held by catches at positions a distance 4.50×10-2m on each side from thecenter of the rod, and the system is rotating at an angular velocity 31.0rev/min . Without otherwise changing the system, the catches are released, and the rings slideoutward along the rod and fly off at the ends.A) What is the angular speed of the system at the instant when the rings reach the ends of the rod? answer in rev/minI keep getting 4.96 and 1.58 but thats wrongB)What is the angular speed of the rod after the rings leave it?answer in rev/minPLEASE HELP!
