    Thank you very much for your help. I figured it out. Couldn't have done it without help. :smile:

    Deriving a formula that an old physicist showed me.

    So I was able to derive the second half of the problem from 1/2at^2. The part that I am actually stuck on is the first chunk. I don't understand how ViT derives to XfTan(Theta) I got T = Xf/VCos(Theta) But somehow Viy*T = Xf Tan(Theta). Not sure how to derive that.

    Homework Statement I was shown a formula by a physicist I met through a friend when I asked for help with a homework problem. I needed to find y final for a motion in 2 dimensions problem. He showed me this: Y1 = X1 * tan(Theta) + (Ay * X1^2) /( 2 * V0^2 * cos^2(Theta)) Y1 = Y final X1...
