8PRACTICE PROBLEM
A tiny sphere of mass 125 g revolves in a vertical plane around a horizontal axis at the end of a cable of length 80 cm. What should be the minimum angular acceleration of rotation in order for the sphere to complete a full revolution without the cable becoming loose at the highest position?
