In the figure, a uniform rectangular create 0.40 m vide and 0.1 m tall rests on a horizontal surface. The crate weighs 540N, and its center of gravity is at its geometric center. A horizontal force F is applied at a distance h above the floor. If h=0.65m what minimum value of F is required to make the crate start to tip over? Static friction is large enough that the crate does not start a slide.
