Ladder Fails

A ladder is leaning against a vertical wall, and both ends of the ladder are at the point of slipping. The coefficient of friction between the ladder and the horizontal surface is 𝜇1 = 0.185 and the coefficient of friction between the ladder and the wall is 𝜇2 = 0.103. Determine the maximum angle α with the vertical that the ladder can make without falling on the ground.

A painter climbs a ladder that is 2.75 m long leaning against a vertical wall. The ladder makes an angle with the wall which is 30.0°. The mass of the painter is 75.0kg.(a) How much work does gravity do on the painter?(b) Does your answer in part (a) depend on whether the painter climbs at constant speed oraccelerates up the ladder?

Ladder is shutting down 🤦🏻‍♂️😂 #fail #ladder #tradie | Funny Pranks
