Aladder of length l is placed against a smooth wall such that it forms a angle θ with the wall and the friction force between the ladder and the floor is fs .
a. on your paper, derive an expression for the ladder's mass, m, in terms of θ, g, fs, and/or l.
b. try out your derivation. if θ=32° and the friction force on the floor is 47 n, what is the mass of the ladder?
