One end of a spring of spring constant 80 Nm ⁻¹ and unstretched length of 30 ~cm is fixed at point A and the other end of the spring is fitted with a smooth ring of mass 300 ~g as shown in the figure. The ring is allowed to slide on a horizontal rod fixed at a height of 40 ~cm . Initially the spring makes an angle of 60^ with the vertical and the system of spring and ring is released from rest. The speed of the ring
