On the International Space Station an object with mass m = 170 g is attached to a massless string L = 0.61 m. The string can handle a tension of T = 7.9 N before breaking. The object undergoes uniform circular motion, being spun around by the string horizontally. What is the maximum speed v the mass can have before the string breaks?
