hello all, I'm studying from my midterm and having some trouble figuring out the question below..thanks for the help(adsbygoogle = window.adsbygoogle || []).push({});

A uniform ladder of length L and mass m1 rests against a frictionless wall. the ladder makes an angle "theta" with the horizontal.

a) find horizontal and vertical forces the ground exerts on the base of the ladder when a firefighter of mass m2 is a distance x from the bottom.

b) if the ladder is just on the verge of slipping when the firefighter is a distance d from the bottom, what is the coefficient of static friction between ladder and ground?
