The horizontal disk rotates around a vertical axis (Fig. 39; top view). Spring AB is attached at one end to the disk, and at the other to ball B lying on the surface of the disk. The mass of the ball is m = 0.1 kg, the angular velocity of the disks is ω = 50 sec-1, the distance OA is 20 cm, the stiffness of the spring is c = 1500 N/m, and its length in the undeformed state is l = 30 cm. What length will the spring have when disk rotation?
