haha, Thank you so much! My dad is a Physics Prof. over at the University of Waterloo (in Ontario), and he didn't have time to help me with this homework. LOL, oh well. Thanks again!

I think I was reading the numbers off wrong. ~0.46?

Ok so I plugged in a few numbers and tried this. Ff = -Facos60 Ff = -(20N)cos60 Ff = 10N Then: u = Ff/Fn u= 10N / 21.9 N u = ~0.49 Is this correct?

Thanks for the welcome! Purplelgnd is actually a name I made up for a Minnesota Vikings forum that I post on (not a proud day today to be a fan I admit). OK but sadly, I'm still stumped. I'm actually about to break down into tears right now, LOL.

Homework Statement While walking down the hallway, a student drags his 4kg school bag. The force on the bag is 20N [60 degrees above the horizontal]. If the bag moves at a constant speed, what is the coefficient of friction? Homework Equations Fn = Fg-Fasintheta Ff = u(Fn). The...
