Question

A ladder 7 m long and 200 N weight placed against a vertical wall
in a position where its inclination to the vertical is 40°. A man
weighing 400 N climbs the ladder and at what position will he
induce slipping. The coefficient of friction between the ladder and
the wall is 0.4 and between the ladder and the floor is 0.5.
