Puzzle Question : A bear fell from a height of 10 meters from ground. It reached ground in √2 seconds. But somehow, it didn’t get hurt. What is the color of the bear? Answer : In combination, the equatorial bulge and the effects of the surface centrifugal force due to rotation mean that sea-level effective gravity increases from about 9.780 m/s2 at the Equator to about 9.832 m/s2 at the poles, so an object will weigh about 0.5% more at the poles than at the Equator. Taking value of gravity at Polar region as 9.8 =~ 10. Applying N ewtons second equation of motion(s=ut+1/2at^2), times comes to be sqrt(2).Hence bear belongs to polar region, hence it should be white in color.
