If baseball was played on the moon, how far would a Ian Kinsler home run go?
Now I will show the difference of the x and y. We will start with x. So x represents the horizontal distance. Here is a qualitative (estimate) position vs. time graph of x:
Because this is a line, the position changes directly with time. This shows that as the time increases the distance the ball is from the plate uniformly increases. This also means that the velocity is the same horizontally for the entire distance traveled.
Now for y which is the vertical distance. Here is a qualitative position vs. time graph for y:
So in this graph, we have a parabola which means that the position varies with the square of time.
This is most likely why the height which is the y position is 7.5 times the original.
