Mark is trying to rescue Mary from a castle by climbing a uniform ladder that is 5 m long and weighs 180 N. Mark, who weighs 800 N, stops a third of the way up the ladder . The base of the ladder rets on a horizontal ground and leans in equilibrium against a vertical frictionless wall. The ladder makes an angle of 53.1 degrees with the horizontal, and forming a 3-4-5 right triangle. Find the force exerted by the ground at the base of the ladder
