Imagine building a large pendulum by attaching one end of a 3.25-meter-long cable to the ceiling and the other end to a bowling ball that weighs 64.5 N. If you pull the ball to the side, it will swing back and forth in a circular arc. In one experiment you measure the speed of the swinging ball to be 4.25 m/s as it passes through its lowest point (when the cable is vertical). At that moment, find a. the magnitude and direction of the ball's acceleration b. the tension in the cable
