A boy whirls a stone in a horizontal circle of radius $1.73\mathrm{m}$ and at height $1.64\mathrm{m}$ above level ground. The string breaks, and the stone flies off horizontally and strikes the ground after traveling a horizontal distance of $8.99\mathrm{m}$. What is the magnitude of the centripetal acceleration of the stone while in circular motion? Use $g=9.81\mathrm{m}/{\mathrm{s}}^2$. Number Units
