To determine the maximum height that the kicked ball reached, you'll need to look at the graph of the ball's trajectory. Since I can't see the graph, I can't provide the exact maximum height based on the options given (0, 2, 4, 6 meters).
To answer the question, please refer to the highest point shown on the graph. The maximum height will be the value of y (height) at that highest point. If you can provide details from the graph or describe it, I might be able to help you further!
