Spiking a volleyball typically involves an unbalanced force. When a player spikes the ball, they exert a significant force on it, which changes the ball's motion. The force applied by the player (through their arm and hand) is greater than the forces acting on the ball (like gravity and air resistance), resulting in an unbalanced state that propels the ball downward over the net. The key point is that the act of spiking creates a change in momentum, indicating that the forces involved are not balanced at that moment.
