Classical Mechanics, Motion under Gravity, Motion on Inclines

[hotvette]

I had a brilliant idea last night at 3am (why do all brilliant ideas seem to come at 3am when your mind is racing from injesting far too much caffine during the day?) to include a couple of examples using different choices of coordinate systems. So, I did the free falling body and block on incline problems again w/ different coordinate systems. This will hopefully show the impact of choosing an appropriate coordinate system.

Anyway, here goes, and this one is it, done, finished, final, fertig, fini, finito, terminado, befejezett, обработанный, 出来上がる

Very nice! Thanks for showing the impact of different coordinate systems!
