A bullet is fired through a board 10.0 cm thick in such a way that the bullet's line of motion is perpendicular to the face of the board. If the initial speed of the bullet is 4.00 x 102 m/s and it emerges from the other side of the board with a speed of 3.00 x 102 m/s, find the acceleration of the bullet as it passes through the board?
