A uniform plank 6.1 m long rests on two supports, 2.5 m apart. The gravitational force on the plank is 127 N. The left end of the plank is 1.5 m to the left of the left support, so the plank is not centered on the supports. A person is standing on the plank one tenth of a meter to the right of the right support. The gravitational force on this person is 846 N. How far to the right can the person walk before the plank begins to tip
