A child whirls a stone on a string in a horizontal circle of radius 1.5 m and at a height of 2.0 m above level ground. The string breaks and the stone flies off horizontally and hits the ground 13.3 m away horizontally. Determine the magnitude of the centripetal acceleration of the stone just before the string broke. (Use g = 10 N/kg).
