Bah. How I applied it doesn't actually matter in this case, since its a
lickle bit absurd to start with. ;) Net force upon impact (first instant).

LOL. Heh. Glad my little screw up was useful somehow ;) The gravity thing
is just a comparison btw. If you think how hard it is to hold onto 300g,
thats how much force I came up with an arrow striking with. A lickle bit
out. ;)
