ladder of length L = 2.4 m and mass m = 14 kg rests on a floor with coefficient of static friction μs = 0.55. Assume the wall is frictionless. 1) What is the minimum angle the ladder must make with the floor to not slip? 2) A person with mass M = 61 kg now stands at the very top of the ladder. What is the minimum angle to keep the ladder from sliding?
