a 76 kg window cleaner uses a 12 kg ladder that is 5.8 m long. he places one end on the ground 2.8 m from a wall, rests the upper end against a cracked window, and climbs the ladder. he is 2.5 m up along the ladder when the window breaks. neglect friction between the ladder and window and assume that the base of the ladder did not slip.
A) find the magnitude of the force on the window from the ladder just before the window breaks.
B) find the magnitude and direction (angle) of the force on the ladder from the ground just before the window breaks.


Thanks a bunch!
