An 870 N firefighter, F_ff, stands on a ladder that is 8.00 m long and has a weight of 355 N, F_ladder. The weight of the ladder acts at its center, and the ladder is leaning against a smooth wall at an angle of 50.0° between the ladder and the ground. The firefighter stands at a point 6.30 m from the base of the ladder. The ground is not smooth and exerts a force, F_ground, on the ladder to keep it from slipping. Determine the forces that the wall puts on the ladder, F_wall, and that the ground puts on the ladder, F_ground.
