Ahomeowner 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 =0.266 md=0.266 m from the rock, which has a mass of 325 kg,325 kg, and fits one end of the rod under the rock's center of weight. 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? assume that the rod is massless and nearly horizontal so that the weight of the rock and homeowner's force are both essentially vertical.
