Science Homework Help. I need help with a physics problem
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.
