according to the question if i use the equation s=ut+1/2×a×t×t 20=(0+1)/2a4 .where s=distance,u=initial velocity,t =time period,there we get the value of a that is acceleration as 10 and this is the max value of acceleration due to gravity and this would be possible only at poles and either north and south poles and at poles only polar bear exists so the colour of the bear will be white and i think this question was asked in jee advance i dont know about the year but this question was once asked in their examination0Modal content

answer is white bear. because by using equation: s=ut+1/2×a×t×t we get: 20=0+1/2a4 SO acceleration equal to 10.accleration due ro gravity on earth will be only at poles of earth!! so color of bear is white11Modal content

since the bear throws the stone from rest, so his initial velocity will be 0m/s and he is at a vertical height of 20m, so to throw the stone in 2 seconds the bear must be of black color as its a natural thing... if you are stil not satisfied, then you can Google it out too..-1Modal content
