I remember from my high school physics a rather classic problem of a
snowball rolling (falling?) down a hill and impacting a wall. The
question was "how fast does the snowball have to be moving to completely
melt on impact?" I think the magic number was 60 mph; the interesting
thing was that after all the calculations were done, the mass of the
snowball completely fell out of the equations. It didn't matter how big
the snowball was, just how fast it was going...
