Question

a tennis player hits a ball with his racquet. the ball moves away from him and bounces off the ground, as modeled below. which model correctly shows the gravitational force that earth exerts on the ball throughout its motion? choose 1 answer: a image of model a b image of model b c image of model c

Explanation:

Gravitational force exerted by Earth on an object (like the tennis ball) is always directed downward (toward the center of the Earth), regardless of the ball's motion (whether in flight, bouncing, etc.). In option A, forces have non - downward directions; in option B, there's an upward force which is not gravitational (gravity is downward). Option C shows all gravitational force vectors pointing downward, consistent with the nature of gravitational force on the ball.

Answer:

C. The model where all the force vectors representing Earth's gravitational force on the ball are directed downward throughout the ball's motion.
