The very rapid deceleration is known as jerk.
Impact of elevator hitting floor.
Proof of the aircraft in a compilation te.
Remember this is relative to the floor of the elevator.
Will provide a reasonable estimate of the impact force.
You launch yourself upwards at about 2 45 m s.
This means that relative to the ground outside you are traveling down slightly slower at 97 55 meters per second.
In a frictionless fall it s identical physically to falling off a building and hitting stationary floor.
Although the impact force varies with time an average or effective force feff can be assumed which acts over the impact duration t such that feff t t fdt.
So the elevator slams into the ground at slightly more than 100 meters per second because your feet pushed it.
If the elevator has been falling for more time then the injuries would be much more grievous.
Do you think 911 was an inside job.
Hitting the ground floor in this position spreads the force of impact across your body.
Also if you jumped even a little before the elevator struck the ground you would crack your head against the ceiling of the elevator causing even more damage.
In fact betty lou oliver actually survived falling 75 stories in an elevator because she wasn t pressed up against the floor.
But the long ride got a lot worse when one of the cables snapped and the elevator plunged 84 floors to the 11th floor.
18 different views of the second plane crashing in the twin towers in the usa.
Using physical reasoning to estimate the interval t then feff m v t.
More time in free fall more momentum more overall damage.
No you would just hit the floor a split second later with maybe slightly less force than you would have had you not jumped.
You get hurt by a sudden stop it doesn t matter if that sudden stop was from the elevator itself suddenly stopping not jumping or you hitting an elevator that has already stopped what happens if you jump.
It also orients your spine and long bones perpendicular to the impact direction which will better protect.
