Rocket hits ground at 250 MPH

[chopperpig]

hahahahaha!!!!!!!!!!!!!!!!!!!!­!!

[Pineknife9]

Put a video camera on it:D

[fatpanda1011]

whoever said egnition sounds really stupid

[linkinparkfanaat]

what if that thing hit sombody

[HackerGuitarist]

bet you weren't asked back to that clubs field again...lol... was the team certified level 3 ?

[FreshApplePieOnXBL]

I like how it says 500MPH in the video and the title says 250

[zafi04]

so this is basically a fail?

[50caliberslowmo]

now imagine the same thing with a 1million ton meteor going at the speed of sound. and people doubt that THATtook out the dinosaurs?

[harpo103]

Helluva lawn dart!!!!!!!!!

[spunkypuppy]

That'll buff right out...

[DaEliminator]

isnt shooting rockets over a certain altitude like illegal because its in such close range of aircrafts?

[IPlayWithLasers]

Lol

[bowman5454]

If that rocket hit the ground at 250 or 500 mph (make your mind up please) it would have have been in a lot worse condition than the photo suggests. I still think it's a fake, but very nice flight anyway.

[joshuamnr]

@bowman5454 By the way that last post about Galileo's principle was straight from NASA's web page. Argue that if you want but your arguing with NASA. Google NASA terminal velocity open the very first page if you want to learn more.

[bowman5454]

How did you calculate the speed of impact anyway, I think your data is flawed.

[bowman5454]

The falcon powers into it's dive to increase it's speed it doesn't just fold it's wings and fall,

Take a 1lb and a 50lb lead ball and drop them at the same time from as high as you can, they will both hit the ground at the same time, and if you drop them from high enough they will reach 127 mph (terminal velocity) even though the 50lb ball has a much greater surface area than the1lb ball. Air friction only effects very light objects or objects that are heavy but very thin and flat.

[joshuamnr]

@bowman5454 If we have two objects with the same area and drag coefficient, like two identically sized spheres, the lighter object falls slower. This seems to contradict the findings of Galileo that all free falling objects fall at the same rate with equal air resistance. But Galileo's principle only applies in a vacuum, where there is NO air resistance and drag is equal to zero. Check it out your self.

[mattmccury]

@joshuamnr no, the lighter object doesn't fall slower.......

[joshuamnr]

@mattmccury Yes it does. above comment directly from NASA's web page. Google NASA terminal velocity open the very first page if you want to learn more. Don't confuse your own opinion with fact.

[mattmccury]

@joshuamnr no, gravity is a constant at 9.8 meters per second per second, it doesnt change, only drag changes

[joshuamnr]

@mattmccury Terminal Velocity = Square root of 2 x mass x Acceleration due to gravity / density Projected area of object x drag coefficient. Your 9.8 meters per second per second for gravity is in the formula but the mass of an object does effect its terminal velocity. I do strongly suggest you check out NASA's web page on this. I can understand arguing with me. But i copied my comment directly from their page so you are arguing with NASA.

[bowman5454]

Should have said this in my original comment, 127 MPH is known as termenal velocity ( the fastest any thing can fall to earth unpowered.

[headshooter44]

@bowman5454 wrong. the onely thing slowing you down is air friction. at higher altitude there is lower friction and so mutch higher falling speed. and even on ground level there is not really a limmit. it all depends on the mass and the friction. if you have an arrow of lead, it would fall at about 500km/h. there are tests with human dummys made off iron and they fall at speed of about 300kmh. a falcon falls at over 300kmh, when launching an attack. and dont tell me a falcon has a rocketbooster!

[bowman5454]

Unless the rocket was still under power the fastest it could fall is 127 mph this a fake.

[headshooter44]

@bowman5454 ok. and how do you explain the falling speed of a falcon of 320km/h?

[CartoonManiac12]

dang dude...

[waverleyrocker]

how did you get the number 250mph? (or 500mph as it said in the video?) I would think the terminal velocity is much slower than that.

[headshooter44]

@waverleyrocker there is no universal terminal velocity. it depends on airodynamics and mass. a falcon falls at 320km/h without boosters.

[DaGoalieSniper]

If all these wiz kids and everyone else out there in youtube land can build a rocket like this... just imagine what Iran and North Korea are up to

[cippoco]

If it fall over some houses? You are crazy or it's a fake...

[Knabbelt]

fake

[edwinshap1]

why would you measure the force of the rocket lawndarting G's? I'd measure it in pound force or something.

[mikethenascarfan]

that'll buff out

[thalyratv]

shit don´t teach this to lady gaga she´ll kill us all

[danaownsall]

ewww hybrid rockets. solid is the only way to go imo, you coulda stuck a mean M-class in there.

[atourdeforce]

i fly model rockets myself, not to this size, but i have flown upto E, AND F sizes. very impressive, but anyways what i wanted to say was i have made and flownn rockets that take simple camera pictures at 1,500-3,000 ft bloody awesome pics at the lower altitude. :)

[atourdeforce]

@AreaQNH870 is that al, you can do with your life go around calling ppl gay, you know he prob doesnt care what a cunt like you thinks neither do i. only reason im wrighting this is for other ppl to see it. god what a knob!!

[AreaQNH870]

@atourdeforce *writing

[osoch46]

did it barrie its self in the ground

[metin1301]

oh my god

[jonharson]

16" inch deep!! let's get the DOD on the line we are gonna go bunker busting.

[tennisloverkent]

wow, is that supposed to be a big deal?

[xatumiller2]

Yea thats the way i go to work.

[LizzyAston]

lol an egg can kill you in this way

[llib90630]

for sale: 3 ft. tall rocket. needs minor cosmetics

[xXiBMXwitSatanXx]

@llib90630 haha

[domakusi]

that was dangerous

[vitruvian8807]

wow, that is some serious speed!

[vanepico]

bloomin' hell!

[hellbea5t]

that's one deep hole, lmao

[hellbea5t]

oh, i got feet and inches mixed up, lol

[aboo1994]

engine?

[michu070]

were you there? i didnt think so, who are you to say what happened

[roidroid]

were you there?

[grayman1661]

I didn't have to be there. It's basic physics, which is the base science for rocketry. And it doesn't matter how many people did or did not see it, the result would have been the same. Basic physics, man Grab a physics text at the library and do a little reading on gravity. It's not as difficult as it sounds and it does make playing with rockets more interesting if you understand the science behind it.

[michu070]

it was totally destroyed and made a fat crater

AWSOME

[VancouverDriver]

Yer gonna shoot yer eye out!

[TheArtistOfKuroo]

What level motor were you using on that thing? Also check out this video of one some friends of mine made for a Student Launch Initiative experiment (we have 2 SLI teams and placed 1st in the Team America Rocketry Challenge aka TARC this last year.)

watch?v=UaiLbNYig4c

[slatan420]

Simply Awesome.

[spacefannumber1]

lol, sad you didn't get any video of it hitting the ground. That would have made the video perfect.

[MynameisRyanGagnon]

ha nerds!

[marybob321]

tittle fail

[PlanetSledge]

Cool
