a) 23.5 N

b) 51.2 N

c) 60.0 N

d) 73.5 N

e) 81.3 N

This is the first problem I've ever done with the coefficient of static and kinetic friction. I have these formulas; F fr = ukFN; Fmax = usFN

Im not sure if that's all I need. I do know that the Normal force (FN) is 71.8, but I am not sure how to go about finding the "max parallel force". If I solve for "Fmax" I get 71.8, but that leaves out the coefficient of static friction. I think I need help
