A ball bounces on the ground. How do the ball and the ground act on each other?

1.The ball exerts a stronger force than the ground and in the opposite direction.
2.The ball and the ground exert forces on each other with equal magnitude and in the same direction
3.The ball exerts a stronger force than the ground but in the same direction.
4.The ball and the ground exert forces on each other with equal magnitude but in opposite directions.

4. The ball and the ground exert forces on each other with equal magnitude but in opposite directions.

When the ball hits the ground, it exerts a force on the ground, and the ground exerts an equal and opposite force on the ball. This is known as Newton's Third Law of Motion, which states that for every action, there is an equal and opposite reaction. The force of the ball on the ground is equal in magnitude to the force of the ground on the ball, but they act in opposite directions. This causes the ball to bounce back up into the air.
