A 35 kg uniform ladder is leaned against a building. The 5 m tall ladder makes an angle of 60 degrees with the ground. The ladder encounters a coefficient of static friction from the ground of 0.3 and a coefficient of static friction with the wall of 0.42. A painter must climb two-thirds of the ladder to reach a blank spot on the wall. What is the maximum mass that the painter can have before the ladder begins to slip?use the conditions for equilibrium. There are twoa 35 kg uniform ladder is leaned against a building.
