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...
