Describe the direction of the force that makes the ball acquire the maximum tangential velocity for the force applied. Use your equilibrium measurements to find the natural length of the spring, that is, the length of the spring without an attached mass. For each of the following forces, first describe the force (magnitude and direction) and then predict the motion of the ball.
