Catfood... I tried your equation and got totally confused. Am I close if I got 95 or 96
i havent learned this yet and its torture on my mind. i dont even get a whole number
i get like a decimal less than 0 lol
wow
i'm pretty good with math but my highschool physics class has not taught me any of this....
What I can tell you is my answer is a 3 digit number. Not too close to 100 but not too close to 999. I don't want to give my answer partially because I don't want people just come and submit it without doing any work, another reason my answer may be wrong (I have solve some puzzles wrong in the past because of error while calculating)
I think the Blog link is excellent... Basically speaking, here are the equations to use in the same order as appearing below:
A = 5/4 t2 tan(54 degree)
F = rho * A = rho * 5/4 t2 tan(54 degree)
m = F /g
V1 = 4/3 * pi * (r1)^3
V2 = 4/3 * pi * (r2)^3
h = (m/d - V1)/(V2/3 + A)
Test with: h/3* V2 + A*h = m/d - V1
Read the blog for more info. The above 6 equations are the main ones. After getting A, m, V1 and V2 all you need to use is the equation for h... The intermediate steps are derivation steps to show how he arrived at the final equation for h.

I also got a 3 digit number...
im only up to algebra and i skipped two levels but i dont understand any of this
I submitted mine as is (without the decimal). I have a final exam at 7:30 in the morning and simply don't have time to review my calculations. If you folks would see of your answers are close to mine, I'd appreciate it. (it's posted a page or two back) Thanks.
which d is the d in the final equation, d1 or d2
and is V1 the one with the 50 cm diameter or the one with the 30 cm diameter?
That d is the density of steel

oh that explains quite a lot
my answer ended up as 159... which I don't think is right
can someone clear it up a bit
like I said, my answer is kinda in middle of 100 and 999 (not exactly middle or near). I'm my answer is right then, you're a bit far off. But there are a lot of calculation and I'm not confident that my answer is right either.
nevermind I think I got it now
ahh well i dont get it, guess ill check back in a few hours
catfood-
i think we may have come up with the same answer catfood... mine is sort of, but not quite in the middle too...
The 3 digit number I got adds up to 20... anyone else's add up to this?
crud...
mine adds up to 15.
never mind, my number was 4 digits... ugh.. I guess I will go do it again.
