[SOLVED] Spring launcher
A spring is launched to hit a target. The target is at a certain distance and height. How do you find the velocity needed to hit the target? The height and distance of the target, and the angle of the launcher are given.
F=kx
x=[tex]\sqrt{m(v^2)/k}[/tex]
v=[tex]\sqrt{gx\Delta/(sin2\theta)}[/tex]
