Re: Perplexing Toy Problem

Actually your responses do not clear up the problem, although they do
help show why one direction of U1 would be preferred over the other.
(Since what you showed was that we could decide between which direction
along U1 minimized the grav PE.)

However, if you look at U2, it is a totally different beast (it
contains cosines and sines of (2*theta_i), not theta_i).

So, we're back to square 1.
