Problem: An 8 m, 200 N uniform ladder rests against a smooth wall. The coefficient of static friction between the ladder and the ground is .45, and the ladder makes a 60 degree angle with the ground. How far up can an 800 N person climb before the ladder begins to slip? a. 7.8 m b. 6.8 m c. 5.8 m d. 4.8 m I don't know where to start with this problem. Any help would be appreciated. Please go through each step with detail, because I need to do it myself so I understand what I am doing.
