Assume that each "unit" is a meter. This is appriximately how stuff would fall at 9.8 gravity.
Notice that red/blue balls have the same parabola (even though due to perspective, they don't appear same size). Also yellow/green are the same. Black is the highest one and is in the center.
blue is 50 meters high, green is 75 meters high, black is 100 meters high, yellow is 75 meters high, and red is 75 meters high. All balls have x velocity of 10 meters per second (with minor random noise); gravity of course is 9.8 meters per second.
