degrees Question 8. A wrecking ball swings at the end of a 11.2-m cable on a vertical circular arc. The crane operator manages to give the ball a speed of 10.1 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 21.8 with respect to the vertical? Ans: 9.29 m/s footect accelerating animals, for it can go from rest to
