I'm having problems with solving these nonconservative forces problems. The teach keeps pointing to Wnc=(KE+PE)f - (KE+PE)i
As we use this when there is friction present, I'm totally confused on where the frictional or opposing force is involved when solving. I've basically been ignoring the frictional force when solving for instance for vf, or vi, which I'm sure isn't the right way. I don't seem to be able to find an adequate explanation in the AP book or elsewhere.
