Dropping a Giant Rock 467 ft.

[emixam101]

this is crazy sounds lol wow !

[nycjay631]

@deutschland08fn sounds like ur defending a baby killer !!! shut the fuck up freak

[ivocla]

Δx=1/2 g t^2 (without air resistance) = 1/2(9.81)(5s)^2= 122m= 400 feet

[nycjay631]

@deutschland08fn u have a really shitty sense of humor nd i think alotta people will agree wit me

[deutschland08fn]

@nycjay631 No I just don't think it's very funny... Yeah let's make fun of the murder of an innocent child.

[PmacGeo]

stop doing math on their video

[snowrida1]

So sick



[sKoutzyy]

Ancient Bombs!

[caliindica]

You win

[snowrida1]

so sick

[wickedstigma]

MAN! THIS SHOULD BE A SPORT! LOVE IT!

[deutschland08fn]

Alright so the rock had the balls to make the jump. Sooooo...

[LEXUSTKO]

this video was crap

[makedonec94]

Me and my cousin dropped a 45 kg(about 90 pounds) heavy stone in the Vardar river hahaha but that was from 500 meter(about 1500 ft.) shiiit man that was a really fucked up explosion belive me mann....

Cool video by the way... :)

[donziiwww]

Dude its your turn...

[BenMoreland94]

this is the best bad assery on youtube

[skullsk8r]

400k+ views for a falling rock? what is the world coming to these days...

[iforgotwhatiwasdoin]

@skullsk8r and yet you clicked on this video.

[skullsk8r]

@iforgotwhatiwasdoin yep! i didnt say i wasnt interested...

[JulietsMan]

@skullsk8r people are tired of watching atttention whored sticking out their tongues and talking about how sexy their 150 facial piercings are,

[PuffMcCloud]

o_o

[BenMoreland94]

this is awsome

[bfeld67]

that sounds like a freaking 12-gauge

[215jami]

This is what happened to the dinosauers

[bluebuzzardcod4]

that sounds amazing

[yellowcolourteam]

Awesome :)

[sleibhin325]

Dropped a deuce the other day that sounded exactly like that...true story. 

[Wapajama99]

So.....INTERESTING...!!!!(fav+­like)

[bendmak95]

that is awesome

[gtarules1]

That sounded like a tank blast.

[Kiniler]

OMG a giant ROCK!! It's a ROCK and its GIANT!!

[123coolerdanu]

dang tht was a long fall+yall are weak just saying

[ataribay]

Bridge deck height = 467 feet

Gravitational acceleration = 32.174 ft/s

Air resistance coefficient = .161 lb/ft

Free fall time = 5.7 seconds

Free fall distance = 447 feet

Bridge railing = 4 feet

Maximum water depth = 24 feet

Weight of rock = 150 pounds

Free fall velocity = 92.7 miles per hour

[rephaim23]

@ataribay

What? I can't allow this. You have bested me in the nerd department. This calls for an adjustment of my spectacles...

[rephaim23]

@ataribay

If the deck height is 467 ft above the river, and the rail is 4 ft high, then the height from point A to point B is 471 ft, thus free fall distance is 471 feet not 447 ft. I agree the velocity was about 93 miles an hour.

[rightofpeople]

@rephaim23 Deck Height equals the lowest ground point to the deck. Water levels change.

[rephaim23]

@rightofpeople

Well, then the 467 feet is either the height from the bridge roadway to the bottom of the canyon (below the water level) or it is the height from the roadway to the water surface, depending on seasonal fluctuation of the Colorado river.

I have good reason to suspect the measurement is actually the distance between the surface of the water and the bridge roadway, because other bridges (eg Deception Pass, WA.) measure it in this way, probably for vessel clearance etc.

[rephaim23]

But in any case, we are only in disagreement of about 20 or 25 feet, so our calculations are pretty much within 1/4 of a second. Good work.

[MrSkater750]

rip to billy the fish

[GUYwhoPWNEDYOU]

K READ THIS CAUSE IT ACCTUALLY WORKS. YOU WILL GET KISSED ON THE NEAREAST POSSIBLE FRIDAY BY THE LOVE OF YOUR LIFE. TOMMOROW WILL BE THE BEST DAY OF YOUR LIFE HOWEVER IF YOU DONT PASS THIS COMMMENT TO 3 VIDEOS YOU WILL DIE IN TWO DAYS NO, YOU ALREADY STARTEDE READING SO DONT STOP. THISIS SCARY. PUT THIS ON FIVE VIDEOS WITHIN THE NEXT 143 MINUTES AND WHEN YOUR DONE PRESS F6 AND YOUR LOVERS NAME WILL APPEAR ON THE SCREEN IN BIG LETTERS. THIS IS SCARY 'CAUSE IT ACCTUALLY WORKS

Bloody hell

[wangsta231]

oops, didnt see those kayakers!

[wangsta231]

thats actually pretty cool, idk how this video turned into a math equation though...

[robloxkid987]

rapidy press 2

dynocats!

[Badass123420]

Jump

[nycjay631]

casey anthony likes doin this, but instead of boulders she uses small children

[deutschland08fn]

@nycjay631 At what point did you think it was acceptable to say that? Grow the fuck up man... Fucking pathetic.

[TIMRRCLUB]

@nycjay631 LMAO OMG This made my day xDNiceee

[elharold1990]

my math studies indicate this was a fookin big heavy rock that fell well far and made a wicked splash. GCSE's??? pah

[trevor6778]

@elharold1990 with that kind of geniousness you need tah get yah ass up to maine an come smoke a jibbah with a bunch of drunk people in the middle of the woods standin around a 30 ft fire

[townyhawk]

@rephiaim23 the sound of the explosion comes later because of the distance so your "simple math" sux ... atleast its not exactly ;)

[rephaim23]

@townyhawk

Yeah you're right. My calculations are off by ....2 inches. Back to the drawing board...

[Sonicthehedeghog]

He just learned how to do that in his math class the day he posted it. and felt sooooo special he had to let the world know....

[KiLLa4LifeJr]

sounds like a nuke

[skullythebloger]

I just did math with no protection.

[snowboardskater1102]

initial velocity= 0

acceleration = -9.8 m/s

blah blah blah

rounded to 500 feet.

yeah i got an A in my physics class

[xC0LLAP53x1Tx]

keep pressing 5. it sounds like the rock gasping for air

[deadeye382]

close your eyes, click 6, and listen. it sounds like an explosion from the distance :D

[kevinmeehan71]

that was frickin AWESOME!!

[civilwildman]

Whoa... that sounded like a friggin' explosion. :O

[MaidenVoyageMusic]

do a gainer off that shit 

[captainfroghammer]

That's how it sounded when I dropped a fudge monkey off that same bridge after eating a 7-11 burrito.

[truckertwojobs]

2+2=12 lol

[212masterchief]

it sounded like a bomb went off. people near the area were probably like "HOLY S***, RUN!!!!!!!!!!!!!"

[Scriptofmagic]

You killed a fish.

[ShoghiDX]

OH MY GOD A GIANT ROCK. ITS A ROCK, AND ITS GIANT!!!111

[DarthRaukrist]

OMG A GIANT ROCK!

Dude..we haven't even thrown it yet.

Well, it's gonna have to be pretty impressive to beat that Giant Rock...

[digitalmicetails]

at first when it landed it sounded like a gun shot so then when you said oh shit we're out of here i really thought it then i was like no? it happened right when they dropped the rock..

[GiveMeLongshot]

Ahahahaha!!!

[rephaim23]

I just had an epiphany! My newest algorithm will now audaciously demonstrate that F = U*CK , under a slope gradient greater than forty-two rates per minute, which means the rock fell an astounding 468 feet. The implications are simply staggering!

[DemonofdaDesert]

What if the motherfuckers just wanted to drop some rocks off a bridge?He just wanted to see a big Splash! Thats why its cool and worth a watching.

[TheMysteriousSheep]

6x8=nigger umad? nice vid though

[skater98300]

That was fucking cool, I want to try that.

[TheApana]

It was sick how the sound was delayed half a second.

[Multilashy]

16 X 2 = 32

[XXSuicidalFoxXX]

How much would i have to pay you to dress me in a rock suit and then throw me off?

[111222333222lolipop]

m0g a giant rock

[HardstylePiiKACHU]

Dude! i think you might of of killed the little mermaid!!

[bluelight760]

one fucking high bridge

[rephaim23]

@dannythrowdown

Yes, it's amazing. I emailed a certain resident of Maple Falls, Washington who owns the property on which this tree was apparently felled. He says the report is true and he'll send me a photo of the tree if he can locate it in his archives. A columnist from the Seattle Times might run a story on this, and other record Douglas fir this summer.

Think of a tree three fourths as tall as the Space Needle. Other 400 footers were reported, as I have included in some videos I made.

[malofa99]

"Please stop doing math on our video"

ahahahahahahahahahahahahahaha I lol'd so hard.

[sjtom57]

Geez, are you guys that starved for entertainment?

@4wheeldrifting actually that wasnt nerdy at all it shows he has brains and you dont soooo better shut it

[rephaim23]

@sederholma

Hey, thanks for the support dude. But I am a nerd, although I wear contacts instead of glasses.

[sederholma]

@rephaim23 well i am a nerd too and i wear glasses lol and your welcome but nerds rule the world! go nerds!

[rephaim23]

@sederholma

Yeah, we launch people into space 'n shit like that.

[sederholma]

@rephaim23 lol

[rephaim23]

This half second discrepancy between the sound of the splash and the sight of the rock hitting the water can actually help us in estimating the height at which the rock fell. If 1 second = 1100 feet, 1/2 second is 550 feet, therefore the sound took almost a half second to travel up from the splash zone to the bridge, since 550 is close to 467 ft.

[SamSunshine1990]

0:18 for atomic bomb

[Cheesycat501]

Kaiba made 41 channels and disliked this.

[rephaim23]

But your point about the speed of sound is a valid one. The speed of sound travels roughly 1100 feet per second, depending on temperature and humidity.

You are correct to note that there is a delay between the sight of the object hitting the water, and the sound waves which produce the bombshell noise.

Between frame 0:19 and 0:20 there is about a half second discrepancy between the object hitting the water and the sound emitted, which in itself can be used as measuring gauge for the height.

[chazytone]

Some poor fish got crushed by that rock ='(

[bikemylifestyle1997]

i give you 5 dollars if you jump down there.

[nemesivevo]

duchai it means you cool :Dxd

[stevechristy19]

blue jeans - $40

video camera - $150

you and your friends dropping a huge rock off a bridge - PRICELESS

[spaces3345]

omg a giant rock.. ahaha that was cool... && I know many people are getting these omg a giant rock comments! yayaa xD

[rephaim23]

[4wheeldrifting]

@hardknoxxent lol! mind=blown

[mylightside]

Oh my god a giant rock!

[GibsonLesPaulFanatic]

Its not a hundred feet. Honestly if you think that's a hundred feet, you're high. It's 467 as the title says. And the reason they ran is because it's Highly illegal to throw things off that bridge. Large fines for stuff like that. But that was fucking awesome!! Nice!

[blastification]

damn it hit the bottom



[Titan11234]

5 + 2 = 7

[davisotj1]

@Titan11234 that it does

[Bigb2059]

@rephaim23 nice. Actually pretty cool use of smarts

[rephaim23]

This is simple entry level math, not very nerdy.

The rock fell WELL OVER 100 FEET. Actually, WELL over 400 feet.

It leaves their hands on frame 0:14, and free falls for another 5 solid seconds, until right before it turns 0:20, it makes a Bombshell sound. So total fall, was between 5 and 5 1/2 seconds.

Height = 16t^2

height is 467 ft = 16t^2

467/16 = 16/16 t ^2

29.1875 = t^2

sqr root of t^2 is t, or time, and the sqr root of 29.1875 is 5.4,

Thus Time = 5.4 seconds if height is 467 feet.

[MusiconYooTube]

@rephaim23 You calculated the sound of the hit not the sight. Forget about the delay of sound? FUCKING IDIOT GAWWWWL

[rephaim23]

@MusiconYooTube

This Fucking Idiot got 6 thumbs up. Please show me your formula, and estimated height the object fell.

My estimate is an approximation, but clearly shows the stone fell over 400 feet, (122 meters). Maybe I was off, by  "ten feet" or twenty feet. Big Deal.

[TheLonelyRoad16]

@rephaim23 You people gotta lighten up. IT'S A ROCK, FALLING OFF A BRIDGE. Why did they do it? BECAUSE THEY COULD! There was no "deep scientific analysis" behind it. They dropped a big ass stone, over a bridge to see it fall. Perhaps you'd realize that if you stopped showing off and cussing everyone out long enough to read the message in the beginning of the video.

[rephaim23]

@TheLonelyRoad16

Thanks for straightening us out. It is a bit ridiculous for us to be spending whole paragraphs on how far a stupid rock fell off a bridge, and then insult one another. Extreme nerds who have never had sex are the types who gravitate towards these sorts of stupid and meaningless discussions.

Guilty as charged. :)

[gnrfreak25]

@rephaim23 your wrong. youre assuming acceleration is 9.8. in a perfect world it is, but there is a force of drag making it go slightly slower. what now.

[rephaim23]

@gnrfreak25

Yes. I finally met someone who is more of a geek than I am. After reviewing the variables, I contend you are right about that. This could effect my estimation by some odd feet. Feel free to make the necessary calibrations at your expedient pleasure, and in the process get 17 thumbs up instead of my 16.

[gnrfreak25]

@rephaim23 i may be a nerd, but i sir am a lazy ass nerd. and i hate physics, im a chem/finance major.

[MrC6280]

@rephaim23 You need to factor in the time it takes for the rock to reach terminal velocity. That usually takes about 3 seconds.

[rephaim23]

@MrC6280

Well, terminal velocity depends on the surface area, weight and mass of the object in question, it could could take 3 seconds for the object to it, but I haven't run the numbers.

But for a rounded approximation, I think you will find the basic formula gives fairly accurate estimate of the object's fall, perhaps within 10 or 20 fee plus or minus.

[karawugi]

@rephaim23 does this make you happy?

[4wheeldrifting]

@karawugi does this NOT make you happy???

[karawugi]

@4wheeldrifting Nothing makes me happy :(

[SpectrumHalo]

@rephaim23 nerd

[rephaim23]

@SpectrumHalo

Yes, I am a handsome nerd.

[FallOfTheEra]

@rephaim23 Well we just got schooled. 

[coolfella101]

@rephaim23 not trying to be a troll here but I used H=1/2at^2 and got a hight of about 150 ft. using 5.5 sec. as the time the rock was in free fall.

[rephaim23]

@coolfella101

Sorry buddy, but if we had used your math skills in 1969, the first man on the moon would have been some Russian guy named "Nicolai Bolshierukiev" -- instead of Neil Armstrong.

This bridge is called "Navajo bridge" and crosses the Colorado river at the upper extremity of Arizona. The two bridges have a respective height above water: 470 and 464 feet, or something like that. probably varies during the season maybe 5 or 10 feet or some thing.

[coolfella101]

@rephaim23 O I see what happened lol my math wasn't off i forgot to convert to feet at the end.

[rephaim23]

@coolfella101

ok, 150 meters is 492 feet -- so within 25 feet of my estimate. Good job, your math skills are fine afterall!

[kryptofan1]

if i where there i would be so tempted to jump

[MyLIfeStudios]

its 100 feet , but besides that it was awesome , really cool crack at the bottom

[Vassylingsch]

@MyLIfeStudios Way more than 100 Feet! It fell for like 10 seconds

[MyLIfeStudios]

@Vassylingsch its either 100 or 150 , pause the video when they let o and pause the video when you see the splash , its 4 or 5 seconds depending when you click but defiantly not 10 seconds

[3xsssss]

@Vassylingsch 5 seconds..

[joeybuffdaddy]

someone got shot

[MovilleAirsoftTeam]

pause press 6 enjoy :)

[rephaim23]

467 feet. That's 2 feet taller than the highest fir tree ever reported by lumbermen.

[fcukinlegend]

@rephaim23 LOL



[rephaim23]

@rephaim23

Well, actually there was a report of a 480 ft Douglas fir felled in the Black Hills, Wa. State circa 1930, but these needs more documentation . The 465 ft record from Whatcom, Wa has decent documentation in local news papers of the time, and other sources.

[RFT15ify]

It's like throwing a mini nuke in the water xD

wuhu throwing a stone in the river.... im shocked about the vandalism of these guys^^

@petermines yes

[plutoplatters]

@petermines lemme guess .... you're the unimpressed genius ??? right?

[paul8246]

then try use tractor to drop the rock it much heavier than it will shook off like nuke shock wave impacting

[benberkovic]

can anyone please calculate the speed of the rock when it hit the water? as far as i know, the speed of acceleration in a free fall is 9,81 m/s... the rock was falling for 5 seconds, so does that mean it hit the water at 49,05 m/s? which comes out to 176,58 km/h right? 109,72 mph... heh... wicked sick! i wonder if it would have gone straight through a car if it hit it instead of the water...:)
