A small sleeve of mass `m=1//10kg` can move along the diameter of a horizontal disc, which slides without friction along a guide rode. The sleeve is tied to the end of the rod with the aid of a massless spring whose force constant `k=10 N//m`. When the spring is not under tension, the sleeve is at the oscillations of the sleeve when the disc rotates about its axis at the angular speed `omega` equal to a) 6 rad/s, b) 15 rad/s.

Answer

`v= 1.27s^(-1)`,(b) v=0, the sleeve does not oscillate
