A wrecking ball swings at the end of a 10.3-m cable on a vertical circular arc. The crane operator manages to give the ball a speed of 10.9 m/s as the ball passes through the lowest point of its swing and then gives the ball no further assistance. Friction and air resistance are negligible. What speed vf does the ball have when the cable makes an angle of 28.5 ° with respect to the vertical?

The figure shows a ball with mass m = 0.450 kg attached to the end of a thin rod with length L = 0.415 m and negligible mass. The other end of the rod is pivoted so that the ball can move in a vertical circle. The rod is held horizontally as shown and then given enough of a downward push to cause the ball to swing down and around and just reach the vertically upward position, with zero speed...
