8. A 5.44 kg bowling ball is attached to the ceiling by a 3.10 m long rope. The ball is pulled to one side and released; it then swings back and forth as a pendulum. As the rope swings through the lowest point of its trajectory, the tension in the rope is 74.1 N. How fast is the bowling ball moving at this point? a. b. C. Draw and label (with symbols, not numbers) the free-body diagram for the ball. Write out the symbolic equation representing Newton's 2nd law in the radial direction. Calculate the speed of the ball at the lowest point of its swing.
