A question of physics

I'm on holiday. The lifts are well dodgy.

Aside from using stairs (10 floors) I am pondering if one fell 10 floors in a free fall lift, would one have a better/worse chance than free falling 10 floors.

Or is this a kilo of feathers/kilo of cement question?

Disclaimer it's a nice afternoon, wine has been taken Grin

In the UK passenger lifts will lock as the safety brakes engage.
This means you will experience a sudden drop but not the full height

A friend of a friend was in a lift fall before I knew her. This was in a service lift which either didn’t have the brake or was a less effective type and she was in a fall of a few floors.
If I recall correctly she had the impact shock through her legs with fractures, and had an effect on her knees. I suspect also to her hip

A free falling lift would be accelerating at 9.8 m/s2. As it would be if you were free falling. So it's going to hurt no matter what.

Maybe air resistance would come into play but not from 10 floors.

v2 = u2 + 2as S would be about 30 m

So you would hit the ground at 24 m/s

Ouch

Less ouch more 'splash' I should think Shock
