Force has to be applied to the ball.

Explanation: Newton’s First Law says an object’s motion changes only if a net external force acts on it. To make the stopped ball move back toward your friend you need a force (e.g., another kick, a push, or a component of gravity if on a slope). Friction and inertia are not actions you can “apply,” and speed is a state, not something that causes motion by itself.
