Problem

A stone moves in a horizontal circle of radius

0.6\,\text{m}

, completing one revolution in

0.8\,\text{s}

. The string breaks when the stone is at the point closest to a wall situated

3\,\text{m}

away along the tangent direction. Neglecting air resistance, the approximate time the stone takes to hit the wall is a)

0.67\,\text{s}

1.00\,\text{s}

0.64\,\text{s}

0.32\,\text{s}
