A) How much friction force is required along the ground to keep 10. A 72.0 N ladder that is 3.60 m long is placed against a frictionless wall so the base of the ladder makes a 77° angle with the ground. A person with a mass of 526 N is standing with all their weight one quarter of the way up the ladder. A) How much friction force is required along the ground to keep the ladder from slipping? B) What is the minimum coefficient of friction needed to keep the ladder from slipping?
