A homeowner is trying to move a stubborn rock from his yard. By using a a metal rod as a lever arm and a fulcrum (or pivot point) the homeowner will have a better chance of moving the rock. The homeowner places the fulcrum a distance d = 0.288 m from the rock, which has a mass of 485 kg, and fits one end of the rod under the rock's center of weight. d- Assume that the rod is massless and nearly horizontal so that the weight of the rock and homeowner's force are both essentially vertical. The acceleration due to gravity is g = 9.81 m/s². If the homeowner can apply a maximum force of 663 N at the other end of the rod, what is the minimum total length L of the rod required to move the rock?
