To determine the goalkeeper's distance from the goalpost when the ball was kicked, we need to examine the point on the graph where the trajectory of the ball intersects the y-axis. On a standard graph, the y-axis represents the height of the ball, while the x-axis represents the distance from the goalpost.
When the distance from the goalpost (x) equals 0, we are at the goalpost itself, which would be the point where the ball was kicked.
Thus, the goalkeeper's distance from the goalpost when the ball was kicked is:
• 0 meters.
