- Summary: Gravitational Potential energy!
-
- The solution to this problem is simple. When a coin is flipped it
- will *come to rest* in a position that represents a minimum in its
- (gravitational) potential energy. For a real coin this means one
- of its two faces with equal probability - it will never *come to
- rest* on its edge even though it has a finite area because this is
- a metastable state.
-
- Our three sided coin, therefor, should be 1 coin diameter thick. This
- is where the center of mass is at equal heights in each of the three
- states and so each configuration represents an equally likely
- stable state for the coin to *come to rest* after a toss.
-
- What was all that talk about honey anyway :^)
