person whirls a metal sphere attached to the end of a cord in a vertical circle. Assuming the speed of the sphere is constant (an approximation), when would the tension in the cord connected to the sphere be greatest? Explain your answer. (a) At the top of the circle. (b) A little after the bottom of the circle when the ball is climbing. (c) At the bottom of the circle. (d) A little before the bottom of the circle when the ball is descending quickly.  (e) Nowhere; the cord is stretched the same amount at all points
