Figure below shows a ring of mass m and radius r= 2.1 m rotating with an initial angular speed w, see figure. Initially, the two point masses, each of mass m/8, are at rest and located at O. These masses can move radially outward along two massless rods fixed on the ring as shown in the figure. At some instant, the angular speed of the system is 8w/9 and one of the masses is at a distance of 3r/5 from O. At this instant, what is the distance of the other mass from O (in m)?
