But it’s hard to say for sure, as NASA data is based on experimental evidence. And on top of that, every human being is different, with different tolerances. The orientation of the body during acceleration is also important. Humans are tolerant of acceleration in an orientation called “eyeballs”. This would be the position of an astronaut taking off on a rocket, lying back and looking up, such that acceleration pushes the eyeballs to the skull. However, if Guy lands next to his ribs, he can probably only bear about 10 to 15 g.
Let’s see how you would protect a falling man in real life. Suppose someone falls from a building and Guy has the same downward speed of impact (about 17.5 m / s). If you want to end this person on the ground with zero speed, there are two things you can change that would make a big difference. (Remember, the goal is to have a small-scale acceleration that doesn’t injure that person. Maybe instead of 25, it’s about 10 g, though that’s still going to be rough.)
First, you can arrange for people to stop playing something soft and bounce instead of bounce. Acceleration depends on the change in speed (vector). This means going at a speed of 17.5 m / s Down 10 m / s up This is a change of 27.5 m / s due to the importance of the direction. However, if the person stops and does not bounce, it would simply change the speed to 17.5 m / s. With a smaller change in speed, you would have less acceleration, which means less force g. This would keep the collision alive.
The second thing to change is time. If you increase the time that a human stays, you decrease their acceleration. I’m sure he was going at a speed of 17.5 m / s, which is a speed of 39 mph. When you stopped, it probably didn’t cause you any injuries. Because a car brakes for about 10 seconds; so the acceleration is pretty low even though you would have the same speed change as Guy.
In real life, you can increase stop time with something like a progress airbag. They are large inflatable structures that collapse under the influence and are used when filming action scenes in movies. Your car’s airbags are based on the same principle of being safe — or not safer“In a mistake.” If the moving body is stopped at a greater distance, the airbags increase the impact time. which reduces acceleration. Both types of airbags are emptied on impact to prevent people from bouncing back. (That, as I explained in the previous example, is bad.) Of course, an airbag wouldn’t work for the scene Free Guy“You should set it before the fall and find out where the guy will land.”
So the bottom line: The inflatable cushion ring around the guy looks great and creates a fun bounce scene. But given the 25 g acceleration, that landing will hurt.
Unless he’s even a real guy. In that case, it’s okay.
