Nautilus's Animations

I have a complaint about Nautilus's animations.

The gravity that effects his anchor is different for the different animations. This effect can be seen when doing Ctrl 2 and Ctrl 3. The anchor in Ctrl 2 reaches the ground at a later time than in Ctrl 3, even though Nautilus throws it at around the same height.

If we look at the velocities of the two anchors in Ctrl 2 and Ctrl 3 at the instant before the anchor reaches the ground, they are not the same. The final velocity of the anchor in Ctrl 2 is much slower than in Ctrl 3. If gravity was the same in both animations, considering the anchors have the same maximum height, then both anchors should reach a final velocity v before hitting the ground.

Please fix this issue.
