Question:
A bullet is fired through a wooden board with a thickness of 8.0cm. The bullet hits the board perpendicular to it, and with avelocity of +350 m/s. The bullet then emerges on the other side ofthe board with a velocity of +210 m/s. Assuming constantacceleration (rather, deceleration!) of the bullet while inside thewooden board, calculate the acceleration. (Note that the positivevelocities define the positive direction to be in the bullet'sdirection or travel.)
2. Calculate also the total time the bullet is in contact withthe board (in sec)
