    Calculating Angular and Linear Acceleration in a Vertical Plane

    Can someone please help me with this problem: You are swinging a mass at the ned of a string contained in a vertical plane. The length of the string is r. The mass moves just enough to complete hte circle. The motion is a constant total energy and we take the sense of rotation as positive...
