Determine the distances (in metres) to which the 56.1 kg painter can climb without causing the 4 m ladder to slip at its lower end A. The top of the 8.7 kg ladder has a small roller, and the coefficient of static friction between the ladder and the ground is 0.27. Assume (1) The mass centre of the painter to be directly above her feet, (2) There is no friction between the small roller on top of the ladder and the wall.
