A bullet is fired through a board, 14.0 cm thick, with its line of motion perpendicular to the face of the board. If it enters with a speed of 450 m/s and emerges with a speed of 220 m/s, what is the bullet's acceleration as it passes through the board?
 a. -500 km/s2
  b. -550 km/s2
  c. -360 km/s2
  d. -520 km/s2
  e. -275 km/s2

Question 2

A particle is moving at constant velocity. Its position at t = 1.0 s is 3.0 m and its position at t = 4.0 s is 15.0 m. What is the slope of the position-time graph for this particle?
 a. 0, since this is a constant velocity situation.
  b. 4.0 m/s
  c. 4.0 m/s2
  d. 9.0 m/s
  e. 12 m/s2
