🤯 A visual physics lesson at 80 km/h.

@peterbrown @nexta same, I was watching the video looking for a car to show up
-
@nexta who was involved? I'd love to learn more about the planning that went into this.

Ah - I was just wondering what kind of bomb-launching railgun they had in the fuselage!
I'd never heard of the A-5's unusual bomb bay configuration. Wikipedia explains that the payload "was propelled rearward at about 50 feet per second":
@toddz My uncle flew a lot of exotic stuff -- he's the only person I know with a Mach 2+ pin -- and he told me about the A5. I was quite young so I might be responsible for the inaccuracy.

@nexta mythbusters did it without risking anyone’s life
@Kierkegaanks @nexta Where's the fun in that?

@nexta
PS: Don't do this near light speed without changing the formula. A few other practical problems might show up too
@notsoloud @nexta xkcd relativistic baseball
You do not want to be the relativistic baseball. -

Enthusiasts launched a man from a moving truck in the opposite direction - at the same speed the car was traveling.
The experiment spectacularly showed how relative speed works.
@nexta That’s impressive! Logical, but impressive!

@nexta I worry that if I boost, other people might try this!

@nexta this is really cool

Brave man! (even if the physics is correct, you have to trust the machine to work correctly, haha)

I feel like I'd want to have full motorcycle safety gear just in case the velocity didn't match and you wound up unceremoniously yeeted into a slide -

@nexta so this vid is actually interesting?

@nexta It reminds me very much of the classic pendulum experiments where a person releases a pendulum on a long arc and it never hits them because ... pendulum.

@nexta I bet that would be a wild ride, though I would still find a way to bust my butt.

@nexta this marks the end of bus stops.

@nexta That's why if you run to the back of the plane really really fast you drop out of the sky.
As a kid, the cartoon pink panther had this thing where he would step out of the house just before it hit the ground and I spent like half a day figuring out if that would work or not, only to realize it WOULD work if he jumped up at exactly the speed the house was falling when it hit the ground. Alas such a jump was not feasible.@ChuckMcManis @nexta yeah, there's stuff about falling lift/elevator cars and jumping before they hit the ground. Unfortunately, if you're in freefall, you can't jump. Of course, that's besides problems of predicting impact and the car collapsing.

well... if you do not move is an important parameter...- YouTube
