An object of a mass of 8 kg revolves in a circle of a, Ask an Expert

Academics

AN object of a mass of 8 kg revolves in a circle of a radius of 3 mattached by a massless string to the center. There is nogravity or friction. It makes a complete turn every 5seconds. If a constant decelerating torque of 9 is applied tothe mass in order to stop the rotation:

What is the angular acceleration, how long does it take the system to stop, how far in radians will it go, how many turns is this equal to?
