Greetings, in this link there's a picture of a slide I posted it in a thread in which I asked a question, but it got deleted by "Nugatory", because he thought it was a "hw question". My question was regarding the formula on the right "v0x = v * d/(sqrt(d^2 + (h-y0)^2)", asking where the formula comes from. Plus, there are no values in this slide, so you'd only find a general solution, not specific one. I say, it's a concept problem. It seems that the mod who deleted my thread misplaced his judgement. I won't rest until I hear from other mods that they honestly believe this was a hw question. Come on, look me in the eye and tell me.
