Kyle is playing volleyball. After he hits the ball, it reaches its maximum height and then falls toward the ground due to the force of gravity.
Which statement best describes the interaction between the ball and Earth?
The ball and Earth attract each other with equal magnitudes of gravitational force.
O
The ball and Earth produce equal magnitudes of gravitational acceleration on each other.
The gravitational force exerted by the ball is much less than the gravitational force exerted by Earth.
Earth exerts a gravitational force on the ball, but the ball is too small to exert a gravitational force on Earth.
