Homework Help: Physics

Posted by Annabelle on Friday, June 22, 2012 at 11:18pm.

A wooden plank with length L = 7.5 m and mass M = 104 kg is centered on a granite cube with side S = 2.0 m. A person of mass m = 64 kg begins walking from the center of the plank outward, as shown in the figure. How far from the center of the plank does the person get before the plank starts tipping?

The answer is 2.62 m, but I'm not sure as how to go about this problem. I've tried drawing a free-body diagram, but it hasn't really helped me. Any help is greatly appreciated.
