What is the maximum height a person may climb without causing the Ladder to slip. Ladder is leaning against a smooth wall. the angle from the ladder to the ground is 40 degrees. Givens: 4 meter length ladder with a mass of 5 kilograms. static friction of .60. mass of person is 150 kilograms. center of mass of ladder should be at the middle of ladder. A free body diagram would help. Im not sure if there's various ways to solve this problem but we need to use torque specifically.
