Actually, they did numerous test runs with a dummy and at lower speeds with him in the chair. Their crew had quite bit of experience building this style of launcher, and had previously done this stunt on a separate occasion at a lower top speed.
This could revolutionize public transport. Train can just zoom past and if you need to get off you just step into the yeet chair and just get dropped off. Imagine it. A mom with a stroller. Elderly lady with a yappy dog. Just being deposited along the route. And a similar yeet chair can probably deposit you onto the train too. Ok, realistically, it's only gonna happen in say a space asteroid mining anime to get the workers to and from their workspot while preserving delta v. Still fun.
And they say jumping just before your elevator hits the bottom in a free-fall WON'T save you. Pff. If I'm ever in a free-falling elevator, I know what MY choice is going to be.
Having watched the entire video with them, they absolutely didn't trust physics at all. They spent DAYS working up to the 80km/h speed, starting on a gravel road at much slower speeds.
I've seen plenty of the show. Even with planning, getting such percision is still a feat in itself. Either thry got lucky on the timing for it to exit the cannon at the exact middle or thry did the calculations to account for the acceleration, or deceleration and trigger the exact timing rather than eyeballing it, which would have been more than enough for the text being conducted.
I'd argue he didn't need to trust physics. He did put a lot of trust on the people who engineered that machine which pushed him back at the exact same speed as the truck.
You'd have to trust physics since you can argue that physics mathematically simulates the universe as we understand it. There could be a pocket dimension in like Ohio or something where nothing may make sense
Nevertheless I'd still wear a helmet and abrasion-resistant clothing. After all, in theory, theory and practice work the same, but in practice, they often don't.
I was gonna say the same. You don't need to "trust physics", if the truck goes 80 relative to the ground and you're ejected at negative 80 relative to the truck...
For someone who is science oriented, I agree with you. There are people who only believe in a higher power though. So those morons might think physics isn't too be trusted
From someone who is engineering oriented, they did this at low speeds working their way up first to make sure no-one used foot-pounds instead of SI units or something, other than a malfunction there was nothing uncertain by this point.
Thinking about it the cleanest definition is probably in computers, a computer scientist might be trying to work out how an obscure machine works (so you can design others), a computer technician might be trying to find out how to make it work or replace parts (so you can maintain, repair and upgrade it), a computer engineer will be trying to make it run Doom (so you can make it do a thing, doesn't have to be Doom, at least... not once it's been done once before).
There's also a very different focus, science looks at new ways to do things, things that might not even be possible. Engineering looks at -very not- new ways to do things, ways to achieve things you know are (or at least should be) possible and you're just working out how (and you might find it's impractical, science doesn't care about that at all).
Why would he decelerate (horizontally) in the air?
What’s happening is that he mostly-matches the train speed in the middle of each car when he’s going the most horizontal. Then as he starts climbing a ramp, THAT accelerates him in the direction the train is moving, while his own energy is used to accelerate him upward.
When he hits the landing ramp, his vertical velocity is converted to horizontal again, but now he’s slightly behind the train’s pace and has to catch up.
This is the second Red Bull stunt I’ve seen in a week that also has Prada logos on the ramp. That seems like an odd pairing; anyone know what’s up with that?
I really did not know Prada has a sportswear division (Prada is something I just assume to be well outside my price range), so I guess from that standpoint it gives them more exposure

Less trusting the physics and more trusting the engineers to properly apply the physics.

The truck was moving in one direction at the same speed as he was moving in the opposite direction. So he wasn't really moving relative to the ground.
OhIfIMust
Relative to the surface of the earth, the sled *decelerated* him to 0 KPH, just like retro rockets.

Where you trying to explain or sound like a smart ass?

He was part of the build team. They all worked on it on a back road before taking it up to that speed.

This looks like its from some youtube channel so I'm like 75% confident he was one of the people doing the engineering.

The physics isn’t theory though. It’s been proven time and time again. The theory is that the people didn’t screw it up.

The theory may be sound but practical application is paramount.

I was gonna say the same. You don't need to "trust physics", if the truck goes 80 relative to the ground and you're ejected at negative 80 relative to the truck...
Trusting the mechanism and the driver though...

technically we was accelerated to the speed of the ground.

correct. THIS is relativity, not E = mc^2. I should know, I teach IB physics.
sabrinadiesatdawn
I mean, they did this with a dummy that weighed the same as him first. Probably 5-10 times, actually.

AT LEAST. This isn't something you do without THOROUGH testing because it involves a human. This "trick" waas *months* in development
