Homework Help: Physics(Please check)

Posted by Hannah on Friday, June 8, 2012 at 1:15pm.

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 404 N walk on the overhanging part of the plank before it just begins to tip?

(225)(5.0) = (1.1)(400x) = 2.55m

Is this correct? Thank you!
