a ring of mass m=1.2 kg can slide over a smooth vertical rod. A light string attached to the ring is passing over a smooth fixed pulley at a distance of L=0.5 mfrom the rod. At the other end of the string, a mass M=3 kg is attached, lying over a smooth fixed inclined plane of inclination angle 37 degree. The ring is held in level with the pulley and released. Determine the velocity of ring when the string makes an angle a=37 degree with horizontal.
