Problem

A stone of mass

2\,\text{kg}

is tied to a string of length

1\,\text{m}

and whirled in a vertical circle. At the highest point of the path, the velocity of the stone is

v_{\text{top}} = 4\,\text{m/s}

. Determine the ratio of the tension in the string at the lowest point to the tension at the highest point. Take

g = 10\,\text{m/s}^{2}
