The graphs look good. The motion from the release until the first impact is a nice parabolic arc in the y direction (vertical) and little movement in the x direction. On impact the bottle seems to acquire some velocity to the right, which is why the x direction slopes up after time 20. The rise and fall in the air during the first bounce is a nice parabolic arc on the lower graph. Finally there's some random motion at the end, including some motion from midground to foreground, which is why the y direction graph tails downward at the end. Lot's of interesting motion in just this one basic reference! 15 points
