Ok, for our lab on projectile (2-d) motion,

We know :

Angle of launcher(little canon) with respect to surface

height of launcher abover surface

average horizontal distance ball traveled at that angle/height

-9.8 gravity force

and are required to find the launch speed. What equation should I use to accomplish that?

Thank you.
