A 454.0-kilogram wrecking ball is affixed to the end of an 8.2-m chain, which in turn is attached to the tip of a heavy-duty crane. Starting from an angle of 40.5° from the down-vertical, the ball is projected forward (perpendicular to the chain) with a speed of 8.98 m/s. After traveling on a circular path, when the ball comes to a momentary halt on the other side. Find the angle the string makes with the down-vertical when the ball stops. (a) 135° (b) 75.0° (c) 118° (d) 40.5°
