golf club velocity

How do I calculate golf club speed from ball velocity and and coefficient of restitution?
Coefficient of restitution will give the following:
e=(v_ball – v_clubafter)/(v_clubbefore)
Velocity of the ball before is zero, so that doesn’t enter into the equation.
How do I figure out v_clubbefore if I don’t know v_clubafter
Take this free lesson, and show you how physics will uncover the secrets behind the “delayed hand release” and how it impacts the swing speed and distance performance.
Discover the “mechanics and physics” of the golf swing described in “simple and clear” detail that will give you an “undisputable scientific guide” on how to achieve smooth golf swing tempo, improved distance and improved accuracy performance.
