No, please, explain. There are problems on the worksheet that ask for coefficients of friction, and my teacher doesn't explain everything well enough. Sooner or later, she will tell us about this equation (hopefully within the 2 days left before the test)

All they give me is the following:
sled=10kg (pulled across level ground)
sled's rope makes 30 degree angle with ground
rope pulls on sled with 180N
What is this F_f = \mu F_N you speak of? Would that be the total friction = something * net force?

I know what friction is, but how am i actually supposed to implement it into the equation? Like in a problem that asks: Find the the acceleration of the 10 kg sled w/ force of 180 N (also pulling at an angle, but I can figure that out), if the friction to be overcome is 15N (if F > static...
Hello,
I am having some trouble understanding this whole concept about friction as well as force (Newton's 2nd law). What I was told is that Fnet=Ma, which I'm guessing stands for sum force = mass * acceleration.
What I wasn't told is how the units are dealt with. I am very used to...
