A uniform ladder of length L leans against a smooth (= frictionless) wall at angle to the ground. Someone is also standing on the ladder at point D, midpoint between Point C (the center of mass of the ladder) and point B (top of the ladder). What is the smallest coefficient of friction s between ladder and ground which will prevent the ladder from slipping? B D C A Example 2: ladder (Homework 5, bonus mark) Weightless ladder, no friction at B, static friction coefficient at A. MA Given the length L of the ladder, for what values of d will the ladder slip? Will the answer depend on the weight of the person? B Mg = 0 :0 (Homework 5, Bonus mark) d A MA A uniform ladder of length L leans against a smooth (= frictionless) wall at angle to the ground.
