Re: Kicker Help?
We calculated that about 100 pounds of force exerted on the ball with a contact time of 0.01 seconds would launch the ball 20 meters (60 feet). The kicker would contact the ball at 7m/sec which given a coefficient of restitution of 0.7 for a soccer ball means a launch speed of 14 m/sec.
We haven't reached 100 pounds yet. Cocking the kicker prototype part way with a tight elastic spring results in a launch of about 40 feet. We think 60 feet should be feasible using this method.
