- A uniform, 20-kg, 8.0-m-long, wooden plank that is parallel to level ground is supported by two pivots: one pivot is at the extreme left end of the plank, and the other pivot is 3.0 m inward from the extreme right end of the plank. A 80-kg construction worker, who is initally standing on the extreme left end of the plank, begins to walk to the right. How far from the right end of the plank will the worker be located when the plank begins to tip? 4.0 m 4.0 m 5.0 m a. 4.50 m O b.5.00 m O c. 4.25 m d. 5.25 m O e. 4.75 mWhat is the horizontal distance of the center of gravity of the person-ladder system from the point where the ladder touches the ground?B4
