Question

elena is playing catch with her dog, rocky. she tosses a tennis ball, and rocky catches it in the air. then, rocky brings the ball back to elena. which graph could show the tennis balls height above the ground over time?

Explanation:

Step1: Analyze ball - toss motion

When Elena tosses the ball, it first goes up, reaches a maximum height, then comes down until Rocky catches it. After Rocky catches it, the ball's height remains constant as Rocky brings it back.

Step2: Evaluate each graph

The first graph has a constant - height part after an increase, but it doesn't account for the ball coming down. The second graph has a decrease after an increase but no constant - height part for when Rocky is bringing the ball back. The third graph shows the ball going up, coming down, but no constant - height part for the ball in Rocky's mouth. The fourth graph shows the ball going up, reaching a peak, coming down until Rocky catches it (the flat part represents the ball in Rocky's mouth as he brings it back).

Answer:

The fourth graph
