A boy whirls a stone of small mass in a horizontal
P
circle of radius \( 2.5 \mathrm{~m} \) and at height \( 4.9 \mathrm{~m} \) above level
W
ground. The string breaks and the stone flies off horizontally and strikes the ground after travelling a horizontal distance of \( 10 \mathrm{~m} \). What is the magnitude of the centripetal acceleration of the stone (in \( \mathrm{m} / \mathrm{s}^{2} \) ) while in circular motion? \( \left(\mathrm{g}=9.8 \mathrm{~m} / \mathrm{s}^{2}\right) \)
