A light string can support a stationary hanging load of 23.4 kg before breaking.

Question

A light string can support a stationary hanging load of 23.4 kg before breaking. An object of mass m = 2.95 kg attached to the string rotates on a frictionless, horizontal table in a circle of radius r = 0.777 m, and the other end of the string is held fixed as in the figure below. What range of speeds can the object have before the string breaks?
0 ? v ? m/s
