Yup.
Anyway, the more I think about equating energies, the more I realise how many variables there are and how many unknowns. Equating momentums is the way to do I, I just wanted to see if there were others but, alas, they don't teach us what we would need to know to do it this way in year 12.
Anyway, no more responses from me, these database errors are pissing me off. If anyone has a solution, please post it here and i'll *try* to view it.
