In a pinball machine, you launch a very small ball of mass m by pulling on a handle that compresses a spring. The spring has relaxed length Lo and stiffness k. The table on which th spring and ball rest is tilted at an angle as shown in the diagram. Pulling the handle as far as it can go makes the spring compress to a length L. In this initial state, the ball is at rest. When you let go, the handle pushes the ball to launch it. k, Lo m 0 How fast is the ball moving at the moment when it just loses contact with the spring? You can assume there's no friction anywhere and this is happening on Earth.
