See attempt at solution. It has everything.
F_net = ma (net force)
W = mg (weight)
f_k = u_k * N (frictional force - kinetic)
T is the tension force.
The Attempt at a Solution
See attachment below. I realize I just posted a problem related to a two block system. I got help on the last problem and thought I understood it completely, but this time I'm REALLY not sure what I'm missing. I checked over the coordinate system and all the signs in the problem and thought all my steps made sense. Am I simply missing a force?
The answer I should be getting is u_k = 0.25, but I get 0.583 instead.
