Two identical discs are spinning on a vertical rod, at different rotation rates. The bottom disc is on a support, and the top disc is sliding down to hit the bottom one. Two discs are on a narrow vertical pole. The bottom disc is supported, while the top disc slides down. They're spinning at two different rotation rates. Once they hit, they rotate together as a single object. Calculate the rotation rate just after the collision, in rev/s. Bottom rotation rate: 5800 rev/s Top rotation rate: 10600 rev/s Mass 430 grams Radius 19 cm
