Sorry, I went back and viewed the video. The ship's vertical speed is far faster than what you are estimating as she drops vertically in one second nearly four ship heights while still showing the the same forward velocity of about 344 m/s. So they have a forward velocity of 344 m/s and slam into the ice with a horizontal velocity of around 250 m/s 5.8 TJ. Also you can see at 0.42 that the ship's bow is digging into the ice with it's leading edge, thus the energy is more concentrated that you are claiming. In addition, recall earlier the ship sheering through the ice mountain's peek with a forward velocity of 344 m/s and 40.46 TJ. Not to mention the slide out after impact still has the ship plowing through the snow and ice at well over 250 m/s. No matter how you try and slice this, it's a very impressive showing since the saucer section is raised up (they may be generating lift at this speed), and the front face of the deflector dish is taking the brunt of the forward impact.Mr. Oragahn wrote:I believe the vertical speed wasn't that high. With half that speed (that would be about a vertical speed of half the length per second), you get a figure that's four times lower.
Figures on Internet show that the ship is only 62~66 meters high. Going for 64 m/s, the KE figure is 28.89 times lower (1.4 TJ).
