A bear falls down to a hole. It falls down to 20m deep after 2s. What's the colour of the bear? From: Chinese Advance Level Examination
The bear is White... A hunter walked one kilometer south from his camp. Then he walked one kilometer west. There he shot a bear. Then he walked one kilometer north, and found that he was back at his camp. What color was the bear?
I am a physics teacher. Only in the polar regions does A = 10m/s^2, hence the bear must be a white polar bear
The bear fell 20m in 2secs… The average acceleration due to gravity is 9.8ms^2 However this is an average. You will get a different acceleration at different points on the earths surface because the earth is not a perfect sphere in fact it is more like a squashed orange. At the equator acceleration is lower than the average because the earth is wider at this point and at the poles the distance from the centre of the earth is less and so the acceleration due to gravity is higher in this region…
Too much shooting of the bear is going on here...... Financial markets world over can perhaps take help of this shooter to shoot down the bears who are on wild rampage.... Regards, RightMan
WHITE....!!!! 01. The bear has fallen from a height of 10 m 02. It took square root(2) sec for it to fall. 03. Obviously it's initial velocity is zero (since it's a freely falling body). 04. Let's assume the acceleration due to gravity is: 'a' meters/seconds square at that place. 05. So applying the formula.. S = ut + (1/2*a*t^2) we know... u = 0, S =10, t = square root(2) secs Hence, 10 = 0*sqroot(2) + {(1/2) * a * 2 } 06. Solving the above equation gives a = 10 meters/seconds square 07. For a free falling body 'a' is the gravitational pull which is g=9.8m/s^2 08. Hence at that place where the bear fell, the acceleration due togravity is the highest (its greater than 9.8 and since wkt a) 09. This can happen only at the poles .. (North or South) 10. And we know that only polar bears can survive in the sub zero temperatures of the poles 11. And no points for guessing that the colour of a Polar bear is WHITE!!!
The bear should be red in color as it would definitely "CRASH" after a 20 M fall, thus bleeding badly.
hm... down a 20m hole with no lights? the bear is black. unless the hole is in a glacier or something, in which case the bear is blue.
1 KM south + 1KM west + 1KM north != Complete square. Thus by proof of contradiction he did not land at his camp, unless his camp is a KM long at which who the hell would have that. Diagonals are also longer than 1 KM thus your theory is false. Also, if it even was remotely close, the bear would be either Brown or black.
