    @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.

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

      @loke @vxo @nexta I wonder if that's also the reason for facing rearward in that curled position? It seems like quite a good one to avoid broken legs. Of course, if he was fired too fast...

      @GerardThornley @vxo @nexta yes. In that position, if you simply straighten your body you'll be standing up. The entire video is quite interesting. They work themselves up from slow speeds until they get to 80 km/h.

        @loke @vxo @nexta I sort of assumed (hoped!) they did a lot of tests so confidence would be high for the high speed run. I must watch the full thing.
        TBH, my first thought on seeing this clip was "that's cool! I want a go!" I wonder how long until this is an extreme sport option for visitors to New Zealand? 😏

          @GerardThornley @vxo @nexta the way he explains it in the video really makes me want to try it. As soon as you are launched everything apparently shows to a halt and then you just stand up.

              🤯 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.

                Yeah, it must feel strange the first couple of times. The acceleration must be pretty wild – that's basically 0-50mph in about 1s.

                It's funny, I assumed they must have some sophisticated powered closed-loop control system to match the catapult speed with the vehicle. But, no, it's just bungee cord, dummy tests and careful driving, lol.

                Only thing I'd worry about is the seat repeatedly hitting the end of the track at 80kph. I hope its well constructed!

                  @nexta Like that time in college where I was able to get a Cessna 152 to “hover” as my airspeed was slightly above stall speed and matched the speed of the headwind.

                      @stragu @nexta Hey! It’s taken from telegram channel in russian, then translated into English and posted here. I don’t thing there is any source for image alt text (only AI probably but it’s expensive)

                          @GerardThornley @nexta @loke Hah, I don't think I've even been on a roller coaster that has that kind of acceleration. The fastest I've been on is The Hulk which launches from 0-40 mph in 2 seconds. That thing is wild, apparently they had to install a flywheel generation plant to keep it from dipping the power to the entire Orlando metro area every time it launched.

                            @GerardThornley @nexta @loke It surprises me someone actually made them take mitigation steps - Florida Power & Light used to gleefully deal with things like a new shopping mall overloading feeders off a particular substation by cutting power to the residential customers on that sub during hot summer afternoons then shrugging their shoulders and walking away
