A puck of mass m = 0.095 kg is moving in a circle on a horizontal frictionless surface. It is held in its path by a massless string of length L = 0.36 m. The puck makes one revolution every t = 0.45 s. a) What is the magnitude of the tension in the string, in newtons, while the puck revolves? b) The string breaks suddenly. How fast, in meters per second, does the puck move away?
