www.karlscalculus.org:Wile E. Coyote stands on a cornice at the rim of a canyon, holding an Acme anvil. Far below, a bridge spans the canyon. On it there is a pile of birdseed. The Roadrunner zips along.......At what times other than before Coyote releases it and after it arrives on top of his head is the anvil at a standstill?
