According to Newton's Third Law of Motion, for every action, there is an equal and opposite reaction. This means that when the player kicks the soccer ball with a force of 5 N, the ball also exerts a force of 5 N back on the player's foot.
The direction of the force the ball exerts on the player's foot is opposite to the direction in which the player kicked the ball. Therefore, if the player kicks the ball forward, the force exerted by the ball on the player's foot is backward, towards the player.
In summary:
- Magnitude of the force exerted by the ball on the player's foot: 5 N
- Direction: Backward (opposite to the direction of the kick).
