Quite likely where the limit of the sturdiness of bones and organs lies. It’s not unreasonable to have a point where important parts fail no matter how you are hit or land, below which it’s more unlucky hits that do damage to specific parts of your body that cause death.

iirc kinetic energy is mass times velocity squared, so the energy increases much faster than the velocity above a threshold
