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. ---

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? 😉 ---

2x20 = 40; 0x404040 = dark grey! 🙂 phyics? ---

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. 😛 ---

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! ---

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

um… er… yeah but I tohught exactly the same thing so… we’re both right! :beam: ---

No, no need to explain, just a simple “Kit, you’re absolutely right as always, we bow to your intelligence” will do fine. 😉 ---

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: ---

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

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

What? Jealous? Moi? Considering I explained how you would work it out before anyone else? I think not, o multi-eyed one. 🙂 [Next page](https://forum.kirupa.com/t/physics-question/28497.md?page=2)
