Force has to be applied to the ball.
Reason: to make the ball change direction (accelerate back toward your friend) there must be a net force on it (Newton's 2nd law). Friction typically opposes motion (it would slow or stop the ball, not make it return), "speed" is not something you apply (it's a consequence of motion), and "inertia" is a property that resists changes in motion, not a cause of motion.
