is attached to one end of a massless string length the other end of which is attached to a fixed support O The mass swings around in a vertical circle as shown in figure The mass has the minimum speed u 5g necessary at the lowermost point of the circle to keep the string from going slack u 5gl If you cut the string when it is making angle 0 as shown in the figure with vertical line through centre O of the circle the resulting projectile motion of the mass has its maximum height located directly above the center of the circle Find the value of 10 cos 0
