I would expect that any commercial car can go 420mph if you drop it from high enough.
Ok now I need to run a cfd sim to check the terminal velocity of a car...
What's the outcome?
I unfortunately don't have a cfd program, nor the skills to use one yet. Should by next year, definitely looking forward to it.
I need a 'remind me in a year' feature!
Evil Kanieval the stuntman figured out the terminal velocity of a human to be around 80 mph or so I believe, i imagine a car would be same or less, although it would probably fall engine side first?
If not, there's always trebuchets.
There are few discussions I have in my daily life that can't be made more entertaining by adding "If not, there's always trebuchets."
Thank you for enriching my future conversations!
If it doesn't work out, there's always trebuchets.
Terminal velocity is a thing that exists.
Drop it from outside the atmosphere. It will hit 420mph probably
Well sure, that’s why I couched it with “I would expect.” My guess is that most cars, even the Peel P50, have enough mass to surface area ratio to reach 420mph. But I haven’t done the math.
Pretty sure I've never seen anyone else use the phrase "couched it" in this context. Well done.
I mostly use it with couching lances in Mount and Blade.
Also valid!
I wasn't sure myself, so I just asked ChatGPT. It gave me a bunch of math that I don't understand and said the terminal velocity for an average car being pushed out of an airplane is 522 km/h (325 mph). I have no idea if that is right or not. LOL.
Why post this then? Anyone could do the same thing (and probably get different results). You added nothing except probably misinformation. Write comments yourself, and do enough research to figure it out yourself, or don't. Don't involve AI slop. We've got enough people we don't need to fill the space with junk.
I did write the comment myself. The rest of us are having a fun and casual conversation. Maybe climb down off that soapbox for a minute and have some yourself.
I'm never going to not tell people to stop including bullshit AI generated stuff they can't be bothered to double-check themselves. Best case, your wasting everyone's time reading it. Worst case is much worse.
Looks like a human is somewhere in the range of 200-300mph, give or take a bit. A car is probably higher, but it really depends on orientation. I wouldn't be surprised if a car couldn't surpass 420mph.
Oh wow, you're right. I always thought terminal velocity for a human was 120 mph. That must have been something I read a very long time ago that just stuck with me. I checked just now and the site I found said that it's 89 mph spread eagle and 310 mph head down. I agree, that car is totally doing 420, dude!
Blaze it!
Just go high enough that drag is negligible. :)
No, terminal velocity is somewhere around 110mph I think. Unless you're talking about sending it into space.
Edit: yes I have read more about this since making the comment. Big thanks to a mediocre education decades ago for what I thought I knew.
Terminal velocity depends on the drag profile and weight of an object. So it actually depends what shape the vehicle is and it's mass.
Pretty sure that's terminal velocity of a falling human. It will likely be much higher for a car.
To be fair, I did say “high enough.” Get it beyond the atmosphere and it’ll easily hit 420mph. Just know there won’t really be anything left for your insurance company to appraise.
I caught that and I tried to acknowledge it. But I think the implied part was that vehicles won't go that fast under their own power.
Sure, that’s why what I said was funny. 😉
