**Problem:**7. A uniform ladder of mass (\(m = 15.0 \, \text{kg}\)) and length (\(L\)) leans against a frictionless wall, as shown in the figure. If the angle \(\theta = 56.0^\circ\), find the static friction force between the ladder and the floor when a 70.0-kg person stands three-quarters of the way up the ladder?[Input Field] \(\_\_\_\_\) N**Diagram Explanation:**The diagram shows a right triangle formed by the ladder, the wall, and the floor. The ladder is positioned such that it makes an angle \(\theta = 56^\circ\) with the floor. The point where the ladder touches the floor is the base of the triangle, and the ladder itself is the hypotenuse, labeled as \(L\). The wall provides no friction, while the floor requires a static friction force to keep the ladder in place when the person stands on it.

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 ?=0.288 mfrom the rock, which has a mass of 465 kg, and fits one end of the rod under the rock's center of weight. If the homeowner can apply a maximum force of 671 N at the other end of the rod, what is the minimum total length ? 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. The acceleration due to gravity is ?=9.81 m/s2.
