Answer:
To determine the time when the ball reaches its highest point, we need to look at the graph provided.
1. The highest point of the ball's trajectory is the peak of the graph where the height is maximized.
2. Identify the point on the graph where the height is highest.
3. Determine the corresponding time value on the horizontal axis at this peak point.
4. The time value at this peak point represents the number of seconds that have gone by when the ball is at its highest point.
By locating the peak of the graph and identifying the associated time value on the horizontal axis, you can find out how many seconds have elapsed when the ball reaches its highest point. This time corresponds to when the ball is at its maximum height during its upward motion.
