sorry if it seems nitty, but guess i am used to working on well defined problems. i guess its normal in physics (at the introductory level at least) to assume away a lot of factors, even if they aren't always stated.

i automatically answered 0 without a second thought. i wasn't trying to be clever or overly-analytical, it wasn't until after the test that it occurred to me that it could be interpreted otherwise.
