1.	One end of a spring of natural h and spring constant k is fixed at the ground and the other is fitted with a smooth ring a mass m which is allowed to slide, on a horizontal rod fixed at a height h as shown in figure. Initially the spring makes an angle of37^(@) with the vertical when the system is released from rest. Find the speed of the ring when the spring becomes vertical? [cos 37^(@)=4//5]
Answer» `hsqrt(k/m)` `h/2sqrt(k/m)` `hsqrt((2K)/m)` `h/4sqrt(k/m)` ANSWER :D
