1. Problem
I have a horizontal cylinder with a ball in it. What must the initial pressure be to launch the ball at Z velocity?
2. Attempt
P = F/A
A = Surface Area(Cylinder) - 1/2 Surface Area (Ball) = (2πrh)
F = m*a
U = - ∫ F dx
U = 1/2 mv^2 at x = h
∫ a dx = -1/2mv^2 / m at x = h
Z = -1/2v^2
This is where I am stuck. How can the final velocity be 1/2 final velocity squared? Any help would be greatly appreciated
