U=0m/s, S=20m/s t=2s  put them into the formula..

20=0+½2²a

a=10m/s²


the accelleration of gravity (g) becomes larger from equator to the pole, because the earth is not really round. so the bear must be in either of the poles. Since there's no bear in South pole, so the bear must be in the north!! and the only bears that live in north pole is----White!!!
