Review Conceptual Example 7 before starting this problem. A uniform plank of length 5.0 m and weight 225 N rests horizontally on
two supports, with 1.1 m of the plank hanging over the right support (see the drawing). To what distance x can a person who weighs
386 N walk on the overhanging part of the plank before it just begins to tip?
