0,01kg bob weight which can be regarded as a material point, 0.1m long thread is attached to the center of the disc rotating in a horizontal plane about an axis passing through its center. 0.15 m radius of the disk, the weight 0.2kg. The system has an angular velocity of 10 s -1 ^. Thread fusible and sinker pulls back on the edge of the disc. Determine the angular velocity of the system, if the sinker is rotated together with the disk, keeping it at the edge.
