I was walking by this building a few days ago. It has a very distinct architecture, the bottom of it starts curving away from a vertical plane. Where the building meets the street it's probably at a 10° angle off from the vertical, or even more (I didnt have my protractor with me:( ).

So I was wondering, what shape would this building have to be to make a fall off the roof survivable for a human being?

Assuming that, we keep the height the same, 190 meters. The person doesn't have a running start. The facade of the building is a single material, with a low friction coefficient.

Is this something that is even possible to calculate? Or is it meaningless because there are countless examples of shapes?
