Why can’t you prevent injury in a falling elevator by jumping at the last second?
Let's say that you and the elevator are moving downward at a velocity of about 100 meters/second just before impact. You jump upwards at about 10 m/s. This means that your final velocity at impact is 90 m/s downwards.
The Short Answer
Let's say that you and the elevator are moving downward at a velocity of about 100 meters/second just before impact. You jump upwards at about 10 m/s. This means that your final velocity at impact is 90 m/s downwards. If that won't hurt you, and the falling pieces of the elevator coming down on your head at 100 m/s don't hurt you, then you're golden.
