A uniform ladder whose length is 5.0 m and whose weight is 400 N leans against a frictionless vertical wall. The coefficient of static friction between the level ground and the foot of the ladder is 0.46. What is the greatest distance the foot of the ladder can be placed from the base of the wall without the ladder immediately slipping?

Suppose a ladder of length L = 8 m and mass m = 20 kg is leaning up against a wall such that it makes an angle of θ = 70 degree angle with the floor and is not moving. For this problem, we'll say there is no one standing on the ladder. As we did at the end of discussion, we'll also imagine that the ladder is up against a very smooth wall so that there is no frictional...

A uniform ladder of length L and weight w is leaning against a vertical wall. The coefficient of static friction between the ladder and the floor is the same as that between the ladder and the wall. If this coefficient of static friction is μs = 0.370, determine the smallest angle the ladder can make with the floor without slipping. ° Please show work thank you
