Two paper screens A and B are separated by a distance of 100m. A bullet pierces A and then B such that the hole in B is 0.1m below the hole in A. If the bullet is travelling horizontally at the time of passing through A, calculate the velocity of the bullet when it hits the screen A. Neglect the resistance of the paper. Take g = 9.8m/s^2.
