A bullet is fired through a board 10.0cm thick in such a waythat the bullet’s line of motion is perpendicular to the face ofthe board. If the initial speed of the bullet is 4.00 x 10^2 m/sand it emerges form the side of the board with a speed of 3.00 x10^2 m/s, find (a) the acceleration of the bullet as it passesthrough the board and (b) the total time the bullet is in contactwith the board.
