A uniform ladder of length L and mass m1 rests against a frictionless wall. The ladder makes an angle θ with the horizontal. (a) Find the horizontal and vertical forces the ground exerts on the base of the ladder when a firefighter of mass m2 has climbed a distance x along the ladder from the bottom. (b) If the ladder is just on the verge of slipping when the firefighter is a distance d along the ladder from the bottom, what is the coefficient of static friction between ladder and ground.
Thank you for the opportunity to help you with your question!
μsw is the coefficient between the ladder and the wall in our problem this is zeroμsf is the coefficient between the ladder and the floor
a = θ angle
thus tanθ= 1 / 2μsf => μsf = 1/ 2tanθ
Please let me know if you need any clarification. I'm always happy to answer your questions.I was wrong the correct problem is here

the coefficitent will be μ = ( m1 * d + m2 * L/2 ) cos(θ) / (m1 + m2) L sin(θ)
the correct forces diagram which accounts for the masses m1 and m2 is in the image
