confession/regret:

i once trew a small piece of stone from the first gallery (45 meters high) of the martini tower in groningen

 

i couldve seriously injured/killed somebody, so im not too proud of that :thumbdown:

Well, maybe. If it was a small piece, I'd say probably .5 kg, right? At most? So it falls 45 meters (from rest, I assume, if you dropped it) at a rate of 9.8m/s/s. An average person is roughly 2 meters tall or somewhere thereabouts. Time for some math!

 

V^2=Vi^2+2ah V^2=0+2(9.8m/s/s)(45m-2m) V=29.03m/s.

 

If it did hit a person, it would be moving at 29.03 m/s upon contact with their head. But velocity itself doesn't matter; the force occurs when it accelerate. In this case, it'll accelrate to 0 after contact with the head, somewhere around .01s is the usual time for a collision like that. That's assuming that once it hits, it'll stop right there and not bounce or anything, which may or may not matter. Anyway,

 

a=(V-Vi)/t a=(0-29.03m/s)/.01s a=2,903.1m/s/s. F=ma=.5kg*2,903.1m/s/s=1,451.55N.

 

That rock hits with a force of almost 1500 newtons. The force necessary to crack a human skull is 873 Newtons [1]. So yea, that rock might have killed someone. You should be ashamed.

 

Of course, it was probably a much smaller rock than that. I'm just not good with kilograms on a relative size basis. Air resistance would also slow it down a bit, but this gives you a general idea. Also, if someone could check my calculations that'd be great.

Is that work based on the assumption that you don't show up with a flamethrower?

Well, yea. That assumption does make my work invalid, though.

Apparently that Cthulhu thing went on my permanent record. D:

Fixed. :thumbup:

Well if you want to factor in air restistance, we could find the terminal velocity quite easily. The final equation would be a = (W - D) / m, but we'll have to find the drag first.

 

The drag equation will be a bit difficult... it's D = Cd x ((ρ x v^2)/2) x a

 

We'll just have to assume the drag coefficient (Cd) is 0.48, since that's the general coefficient for a rough sphere (Flodder I'll be pissed if that rock was an oval).

 

We'll again assume the rock was a sphere to determine the density (ρ). So the density = m / v, and since it's a sphere, it'll be m / (4/3 x pi x r^3). To over-complicate things and make this one hell of a formula, I think I'll just stick this right into our original drag formula:

 

D = Cd x ( ( ( m / (4/3 x pi x r^3) ) x v^2 ) / 2 ) x a

 

Now to put in stuffs we already know:

 

D = (0.48) x ( ( ( 0.5 / (4/3 x pi x r^3) ) x 29.03^2 ) / 2) x 9.8

 

So to find the radius we'll have to assume again... I think it would be fair to say that the rock could be 8 cm (.08m). There fore the volume of the rock would be 4/3 x pi x (.08)^3, which equals 0.002143573. Thus the density is 0.5 / 0.002143573, which equals 233.2554.

 

Here's the simplified equation so far:

 

D = ( 0.48 ) x ( ( 233.2554 x ( 29.03 ) ^ 2 ) / 2 ) x 9.8

 

Moar simplification...

 

D = 0.48 x 98286.9 x 9.8, which equals 462,341.73.

 

...

 

That doesn't seem right at all, and right now I'm too lazy to go fix it, so I'll just say yeah the rock probably would have killed a person.

I envy the asexual. I absolutely hate the concept of love and sex, and really wish my hormones didn't make me like chicks. If I had a choice, I would not only abandon sexuality but also discard all emotions except those that make me appreciate good music/art/food/etc., humor, and satisfaction (e.g. woot finally 99 wc ftw lolz/woot just designed the new iWatch that will sell millions ftw lolz). Because to be honest, sex is a really disgusting thing, it's a shame it feels so good and so many people (especially my age) crave it so damn much. It sucks being a teenager male human.

 

Aaaaaaanyways, the confession I actually came to this thread for... I used to use guide books a lot on video games. Up until a couple years ago, I would use a guide book on any video game I bought, even Pokemon games. So to make things right I've decided to replay Ocarina of Time again, but this time without a guide book. It's a bit unfair since I've beaten it maybe 5 times, but it isn't like I've memorized the dungeons yet. The child parts were a piece of cake, though the adult is a different story... Forest temple was going well until I ended up stuck in a wallmaster room for a good 5 minutes because I couldn't find a key, so I just said screw it and saved and turned the game off >.>

hmm... lol a bit...meh, i cant word it out :unsure:

 

confession:

I with a cousin,once chased after a chicken on his(my cousins)uncles farm

 

the chicken ran into 2 conviniently placed dobermans,you can guess what happened after :wall:

I swear way too [bleep]ing much.

Same here. Get's annoying when I'm somewhere I can't swear, ie home.

A couple days ago I dropped the F-bomb really loud, then looked down to see this little girl, probably about 5 or 6, staring at me. Good thing her mom didn't hear. :???:

 

Regret: Having been me, in September-October. Looking back, I realize that at the time, I was exactly the kind of person I hate now. :shock:

Hahaha, I hate it when I do that. It's really akward. One time, I did it at Wendy's with my crew (both brothers and friend) and I dropped it really loud an some 4-year-old saw me. They stared at me until they left. :lol:

What is really awkward is getting used to using the N word (ironically) a lot with your friend and then going out in public and almost saying it. >_<

I swear way too much lol. Then again, I'm more often pissed off than not.

Why is profanity "bad"? :/ I never understood that... Then again, I don't understand a lot of stupid social things :rolleyes: (Serious question, though... I'm not just trollin' :twss:)

Well that's a whole other can of worms.

 

To save OT, we won't open it.

I've thought about this before, i mean, swear words are the same as every other kind of word but we associate them as being bad and whatever but it's why we think calling someone a [bleep] is a lot more offensive than calling someone a twit. Both are offensive but obviously the censored one is more so. There's probably some historical reason for it thats stuck with it through the ages. Who knows?

I think it's stupid. The words are only as bad as people make them out to be. If people didn't take things too seriously, there would be no "swear words."
