A wrecking ball swings at the end of a 14.4-m cable on a vertical circular arc. The crane operator manages to give the ball a speed of 13.5 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 v/ does the ball have when the cable makes an angle of 14.5 ° with respect to the vertical? Number i Units
