Thanks for the reply Timo!

Why not do it the short way?

Well, I did it the way that came to mind first. I am trying to re-learn
this stuff and things are going slowly.

You have E0 = KEi + PEi = PEi

E1 ( = KE1) = E0 - Wslope

E2 = 0 = E1 - Wflat, so Wflat = E1.

Minimise intermediate calculations, with fewer chances for error. Unless
you need the intermediate results.

You are absolutely right on this point! Many times I set the problem up
correctly only to get an incorrect answer because I messed up in the math.
Back when I did this on a regular basis, I was very methodical and precise.
I guess I feel as if time is running out.

I am studying for the GRE and might possibly take the Physics GRE sometime
in the future. I have been out of undergrad for 6 years and have not done
anything physics -wise since I graduated.

Thanks again!

Will
