Question

How do you find the angle of a fired projectile given the initial velocity and the distance it travels?

Answer 1

Use the formula for range!

Answer 2

so the y=vt-(1/2)gt^2 formula?

Answer 3

Not really.. haven't u derived the formula for range?
if not so.. then.. u can do it conceptually.. consider the horizontal motion!

Answer 4

I haven't learned about derivations yet in math. But would it be something long the lines of
\[y=(vsin(\theta))\frac{ x }{ v_x }-\frac{1}{2}g(\frac{ x }{ v_x })^2\]?
