A uniform ladder of length L and mass m leans against a frictionless vertical wall, making an angle of 49° with the horizontal. The coefficient of static friction between the ladder and the ground is 0.45. If your mass is four times that of the ladder, how high can you climb before the ladder begins to slip?

A 48.2 kg, 3.1 m uniform ladder leans against a frictionless wall. A 97.8 kg person is standing on the ladder down 0.96 m from the top of the ladder. The ladder makes an angle of 57 degrees with the horizontal. What is the minimum coefficient of static friction between the ladder and the ground so that the ladder does not slip?
