A sphere weighing 80N is swung in a vertical circle at the end of a cord 1.2m long. If the velocirty of the sphere at the top is 4m/s, determine the tension in the cord at 150° past the top position.Find also the minimum velocity at the bottom that will keep the sphere along the circular path at the top.
