>Except terminal velocity actually reduces over a certain height due to wind resistance, otherwise parachutes wouldnt work.
Parachutes increase the effective surface area of a human body, essentially making the resistance from the air slightly less than the pull from gravity. This slows down the person, resulting in them falling to the ground at about 2-3 meters per second. Literally the only reason parachutes exist is to avoid people hitting the ground at terminal velocity and spreading their entrails out over a few square meters.
>A specially made safety net could handle that scenario perfectly.
The average weight of a human male is 80 kg. The terminal velocity for this person is about 200 km/h.
If you've ever read anything about fighter pilots, astronauts, or F1 drivers, you'd be aware the largest g-load a human body can take without sustaining extreme damage is about 20 g. Fighter pilots pass out at about 10 seconds of 9g exposure. The average person can not take 5g without passing out in a few seconds.
So, logically if you want someone to survive, maybe you can bring them up to 10g of force in their deceleration attempt and have an emergency trauma ambulance on site to save their life when they land. Let's look at the logic of that.
So, we're going to assume straight off the bat we have somehow managed to bring a 25 meter high safety net here. The person is going to be falling at terminal velocity onto the centre of the net, and the net is going to be about 5 meters wide.
So, at 52 meters per second, the person is going to travel that 25 meters in roughly half a second. To stop him in that distance and time, we're going to be putting about 11g on his body, which is manageable.
But you have to take into account the material used for the net.
The actual force put on this net of yours turns out to be around 8482 newtons.
Name me a flexible material that can take 8482 newtons of force quickly, keep in shape, and not break. Please.
