A homeowner is trying to move a stubborn rock from his yard which has a mass of 1.150 × 103 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 0.288 m from the rock so that one end of the wooden board fits under the rock\'s center of weight. If the homeowner can apply a maximum force of 680.0 N at the other end of the board, what is the minimum total length of board required to move the rock?
