Three unifоrm sоlid disks аre initiаlly rоtаting about an axis through their centers. The yellow, blue, and red disks have masses of 10, 200, and 300 kg and radius 1, 2, and 3 meters respectively. The yellow disk is allowed to fall onto the blue disk in a perfectly inelastic collision. After rotating together for some time, the yellow and blue disk fall onto the red disk in another perfectly inelastic collision. ( I d i s k = 1 2 m r 2 ) Screen Shot 2024-06-18 at 11.27.52 PM.png a. What is the angular speed of the yellow and blue disk after the first collision? b. What is the angular speed of all three disks in the second collision? c. What is the initial kinetic energy of the system? d. What is the final kinetic energy of the system? e. How much energy is lost in the collision process?
