A window cleaner of 57 kg employs a 16.56 m uniform ladder of mass 6.2 kg. He places one end on the ground 2.07m from the wall and another against a cracked window. The window breaks if the cleaner is 1.52 m from the bottom end of the ladder. Avoid friction at the window and suppose the ladder doesn’t slip at its base. Determine the magnitude and direction of the force on the ladder by the ground just prior to the window breaks. Write the force direction as an acute angle in degrees above the ground.
