A ring of mass m =1 kg can slide over a smooth vertical rod. A light string attached to the ring passing over a smooth fixed pulley at a distance of L = 0.7 m from the rod. At the other end of the string , mass M = 5 kg is attached , lying over a smooth fixed inclined plane of inclination angle $$37^{\circ}$$ . The ring is held in level with the pulley and released . Determine the velocity of ring when the string makes an angle $$( = 37^{\circ})$$ with the horizontal.

• Take $$sin37^{\circ} = 0.6$$
