Question

alexandra is teaching her little sister how to play volleyball. alexandra hits the ball gently over the net, and then she and her sister hit it back and forth several times. which graph could show the height of the ball above the ground over time?

Explanation:

Step1: Understand ball - motion physics

The ball's motion is a projectile motion. When hit, it goes up, reaches a maximum height, then comes down. When it hits the ground (height = 0), it bounces back up, but each subsequent bounce has a lower maximum height due to energy loss.

Step2: Analyze the first graph

In the first graph, the ball goes up, comes down to a non - zero height and then goes up again in an unrealistic way. It doesn't touch the ground properly in a consistent bouncing - ball motion.

Step3: Analyze the second graph

The second graph shows the ball going up, reaching a maximum height, coming down to the ground (height = 0), bouncing back up with a lower maximum height each time, which is consistent with the real - world motion of a bouncing ball when hit back and forth in a volleyball game.

Answer:

The second graph.
