    🤯 A visual physics lesson at 80 km/h.

    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
    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 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.

            @anthropy @nexta At the height of Cold War madness, we did this with the A-5: it dumped its bomb load out the back on tracks at up to Mach 2, so it would have zero forward speed at release and drop straight down.
            (It was never used.)

                      @nexta I may be misremembering, but I think Mythbusters wanted to do something like this but it was judged to be too dangerous. This really is very neat!

                          There's also a new podcast with Kari Byron and Tory Belleci called Mythfits and I think they referenced this exact video a few weeks back.

                            @anthropy @nexta Yeah. There's a limited range of speed where you can use speed in the opposite direction to neutralize the effects on a living creature. Beyond that you're headed into Euthanasia Coaster territory.

                                  @nexta many years back, ZZ Top did a similar experiment where you’d sit in a spherical steel roll cage and they’d roll you out of the back of a pickup truck on the highway at high speed.

                                  All was documented in their incredible music: “Master of Sparks”

                                      @pvanheus @nexta IIRC this is a clip from the Japanese TV show ITTE Q, where Nakaoka travels abroad to visit this stunt company to do the stunt (Nakaoka is the one letting go of the spring, not the one in the slingshot).

                                        @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.
