if you jumped from a 100 storey building onto a giant inflatable 'safety bed' - would you still get injured ?
was debating this just now with my brother and he say's yes you would get injured because of the velocity at which you'd make impact with that safety bed.
think giant inflatable bouncy castle. that kinda thing. 100 storey building, thats a tall. thats some jump. could one jump and land on such a thing and not be hurt at all ?

if you drop 100 storys at a 4 meter per story level
the calculations are not finished I used simple example to tell but I got mixed up with the distance as I Did the question;
basically the speed will be faster and that means the speed will be greater and thus the acceleration will be more when slowing down
that is 400 m
your acceleration will be 9.8 m/s/s
that means when you jump off the building your speed will be 9.8 m/s after one second
and 19.6 after 2 seconds
after 3 seconds speed will be 29.4 m/s
after 3 seconds the most you could have travelled is 29.4 + 19.6 + 9.8
which is 58.8 m
after 4 seconds the speed will be 39.2 m/s
then after 5 seconds it will be 49 m/s
when you land safely you have to decelerate from roughly 49 m/s to 0
acceleration like that would hurt say you can stand 3 g's
that is 27 + 2.4 = 29.4 m/s/s
that would need 2 SECONDS to drop from 49 m/s
you could not do that with a inflatable bed

if you land wrong.....you might knee yourself in the head. could happen at one story.
people survive drops like that, but they land going downhill and roll alot to absorb the impact. still break both legs.
if you had a chain o bouncy castles, and they hit each one, then sure.....minus their legs

Depends on HOW THICK the bed is and how fast or slow the air is released to gradually decelerate you. Such "Safety beds" release air upon striking them and gradually slow you down----often used in movies for stunts. I do not know what the record is.

If carefully designed so the bed would decelerate the person safely then it could be done.

people have lived from jumping out of airplanes somehow...thought not pretty,,,so yes you would at least be way way better off than those

depends on the size of this "safety bed". You would be moving at terminal velocity, about 200-300 km/hr depending on angle.
300 km/hr = 83 m/s
if you take 20g as max impact deacceleration, that is about 200 m/s²
v² = v₀² + 2ad
d = 83²/2•200 = 17 meters
in other words, that "safety bed" would have to be 17 m thick. And that assumes the deacceleration is linear, which it is not.
if you take 40g as max impact deacceleration, that is about 400 m/s²
d = 8.7 m

Yes. The force with which you would hit the “safety” bed due to your acceleration and velocity would hurt if not kill you.

Your brother is correct. Jumping from a 100 storied building and then going into the free fall without having anything like a parachute to slow down the sudden deceleration once you hit the safety bed is dangerous. You most likely will be injured.
