Physics hack: The average velocity at constant deceleration is halfway between the initial and terminal velocities.
So if we know the landing speed (which should come out of the flight data recorder), we'll know the terminal velocity given the average speed (distance/time) which is determinable from the video.
No doubt Jeju 2216 was moving hot, but a longer run could have bled off far more speed, and kinetic energy is based on velocity squared, so every bit helps a lot.

- YeGoblynQueenne 2y agoCan't speak about the OP but I didn't weigh a few thousand metric tons as a kid. Or as an adult. I am on a diet though.
- dredmorbius 2y agoSet yourself a goal! And good news! A fully-loaded 737-800 has a maximum takeoff weight of less than 80 tonnes, not thousands, so your challenge is much more attainable! <https://en.wikipedia.org/wiki/Boeing_737_Next_Generation#Specifications https://en.wikipedia.org/wiki/Boeing_737_Next_Generation#Spe...>
- YeGoblynQueenne 2y agoYeah I always overestimate those things by far :)
