I'm compressing a large automotive suspension spring, and then releasing it with a trigger mechanism. The goal is to accelerate a metal plate up to 65 ft/s for a test. How can I calculate the maximum speed I'll get if I know the spring constant, spring mass (wire dia, etc), and the mass of the metal plate?

F^2/2K=mv^2/2
v=F*sqrt(m/K)
where
F is the max force on spring
m=mass of plate
K=spring constant
v=max velocity
First determine F and K from spring formulae.

Correction
v=F*sqrt(1/mK))
