What is the minimum angle to keep the ladder from sliding

Reference no: EM13548484

A ladder of length L = 2.5 m and mass m = 15.0 kg rests on a floor with coefficient of static friction ?s = 0.57. Assume the wall is frictionless.

1) A person with mass M = 63.0 kg now stands at the very top of the ladder. What is the normal force the floor exerts on the ladder?

2) What is the minimum angle to keep the ladder from sliding?
