Problem

A stone moves in a horizontal circle of radius 0.6 m0.6\,\text{m}, completing one revolution in 0.8 s0.8\,\text{s}. The string breaks when the stone is at the point closest to a wall situated 3 m3\,\text{m} away along the tangent direction. Neglecting air resistance, the approximate time the stone takes to hit the wall is (a) 0.67 s0.67\,\text{s} (b) 1.00 s1.00\,\text{s} (c) 0.64 s0.64\,\text{s} (d) 0.32 s0.32\,\text{s}
