But it’s hard to say for sure, as NASA data is based on experimental testing. And besides, every human being is different, with different tolerances. Body orientation also matters during acceleration. Humans are more tolerant of acceleration in an orientation called “eyeballs.” This would be the position of an astronaut taking off on a rocket, lying backwards and looking upwards, so that the acceleration pushes the eyeballs towards the skull. However, if Guy lands next to the ribs, he could probably only support about 10 to 15 g.
Now let’s find out how you would protect a falling human in real life. Suppose someone falls from a building and has the same downward speed as Guy does just before impact (about 17.5 m / s). If you want this person to end up on the ground at zero speed, there are two things you could change that would make a significant difference. (Remember, the goal is to have an acceleration with a magnitude small enough so that the person is not injured. Maybe it is about 10 g instead of 25, although it would still be hard).
First, you could arrange it so that the person touches something soft and stops instead of bouncing. Acceleration depends on the speed change (vector). This means going from a speed of 17.5 m / s down at one of 10 m / s up it is a change of 27.5 m / s, as the direction matters. However, if the person only stops and does not bounce, only a speed change of 17.5 m / s will occur. With a smaller gear change, you would have less acceleration, which means less force g. This would make the collision more survivable.
The second thing to change is the time. If you increase the time during which the human being stops, you decrease its acceleration. I’m sure you’ve been in a car traveling at a speed of 17.5 m / s, which is 39 mph. When you stopped, it probably didn’t cause you any injuries. This is because a car brakes to a stop in a time interval of about 10 seconds, so the acceleration is quite small even though you would have the same gear change as Guy.
In real life, you can increase downtime with something like an artificial airbag. These are large inflatable structures that sink into impact and are used to film action scenes in movies. The car airbag is based on the same principle to keep you safe, either safer“In an accident.” By stopping a moving body at a greater distance, the airbags increase the impact time. which decreases acceleration. Both types of airbags deflate on impact to prevent the person from bouncing. (Which, as I explained in the example above, is bad.) Of course, an airbag would not work for the scene. Free man“You should install it before the fall and know where Guy was going to land.”
So in short: the inflatable pillow ring around Guy looks great and creates a fun bounce scene. But, given its 25 g acceleration, this landing will still hurt.
Unless Guy is real. In this case, it’s okay.
