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?
Answer
Explanation:
Step1: Analyze ball - throwing motion
When Elena tosses the ball, its height first increases as it moves upwards against gravity. Then, due to gravity, it reaches a maximum height and starts to fall downwards until Rocky catches it.
Step2: Match with graph shapes
The height - time graph of an object in free - fall (ignoring air resistance) has a parabolic shape. The ball's height starts from Elena's hand height, goes up, reaches a peak, and then comes down.
Answer:
The graph with a parabolic shape that starts at a non - zero height, goes up to a maximum and then comes down (the third graph from the top - left in the image)
