Homework Help: Physics, Please Help

Posted by Mike on Sunday, November 25, 2012 at 7:02pm.

A homeowner is trying to move a stubborn rock from his yard which has a mass of 1025 kg. By using a lever arm (a piece of wooden board) and a fulcrum (or pivot point) the homeowner will have a better chance of moving the rock. The homeowner places the fulcrum 24.4 cm from the rock so that it fits under the rock\'s center of weight. If the homeowner can apply a maximum force of 696.0 N, what is the minimum total length of board required to move the rock?
