physics question

[radicaljugnu]

didn't know where to post this.

A stone is dropped from a height of 20 metres and takes 2 seconds to fall. It is then picked up by a bear. What is the colour of the bear?

Try answering this, pure physics, IIT entrance exam question.

[eilsoe]

red :)

[radicaljugnu]

no guesswork, eilsoe, anyway you'd have to give a reason. Can't say the bear picked up the stone, smashed himself on the head with it and smeared the blood on him, can you? ;)

[andr.in]

2x20 = 40; 0x404040 = dark grey! :) phyics?

[radicaljugnu]

well, not quite... :sure:

[Kitiara]

As a stab in the dark, I'd say it has something to do with a gravitational pull being slightly stronger in some places than others, so by working out where on the planet that is and how it would affect a stone falling, you can tell what kind (and therefore colour) of bear picks it up?

Female logic is such a devastating thing. :P

[andr.in]

umh Kit I was just gonna post that! But I know the color!

It's a polar bear so it's white and lives on the north-pole where the gravity is stronger!

[senocular]

well it would mean like mars is about 2 inches away if it takes 2 seconds before the rock begins to fall :sure:

It's a polar bear so it's white and lives on the north-pole where the gravity is stronger! So basically, what you'r saying is that I'm <b>right</b> :beam:

[andr.in]

um.. er.... yeah but I tohught exactly the same thing so... we're both right! :beam:

[Kitiara]

No, no need to explain, just a simple "Kit, you're absolutely right as always, we bow to your intelligence" will do fine. ;)

[andr.in]

lol!
Now it's time for jugnu to to come and say that we're both wrong! :P

[senocular]

and another thing, what would a bear have to do with a rock anyway? No bear would pick up the rock thereby meaning the bear is in fact a man in a bear suit - and as we all know, bear suits only come in one color, so the answer is dark brown :crazy:

[radicaljugnu]

kit's right, but not with the full reason. Syko is more right, though.
S= ut + 1/2at²
20= 0 + 2a
a=10 m/s²
And that's only at the poles.
You guys are good...

[radicaljugnu]

well, sen, brown is NOT the only colour you find bears in.

[andr.in]

:beam: see kit :beam:! Bow before your master of all knowledge!

jugnu what language is that? Something scribbleed S= ut? ut=unreal tournament? :P

[senocular]

you mean bear suits
and I was kidding anyway :P

[senocular]

you're just jealous ;)

[Kitiara]

What? Jealous? Moi? Considering I explained how you would work it out before anyone else? I think not, o multi-eyed one. :)

[senocular]

yeah, falsely! My bear suit explanation is the correct answer... but no no no, thats ok. I don't want to steal your thunder. I'll let you live out your life thinking you're right. I may be an absolute GENIUS when it comes to men in bear suits, but Im no meany



:P

jugnu what language is that? Something scribbleed S= ut? ut=unreal tournament? :P Distance = initial velocity*time+1/2*acceleration*time^2 :sigh:

[radicaljugnu]

that should be -
displacement = initial velocity*time+1/2*acceleration*time²

Whatever.

[kirupa]

Jugnu - do you by any chance know what percentage of test takers got that question right? I am going to guess that almost all of them got the value for gravity to be 10, but couldn't figure out the color of the bear...

[prstudio]

the question wasn't that hard...
Physics = Phun!


ROFL sen, that comment about "Male Bear Suit Expertise" was AWESOME ROFL!!!

[radicaljugnu]

kirupa, this is an IIT question, that's why the colour of the bear is just there to confuse people
