A bullet is fired through a board 17.0 cm thick in such a way that the bullet's line of motion is perpendicular to the face of the board. The initial speed of the bullet is 460 m/s and it emerges from the other side of the board with a speed of 360 m/s. (a) Find the acceleration of the bullet as it passes through the board. Your response differs significantly from the correct answer. Rework your solution from the beginning and check each step carefully. m/s2 (b) Find the total time the bullet is in contact with the board.
