    • D. neither velocity nor acceleration is zero.

  2. Below is a plot of the displacement vs. time for two trains running on straight tracks. Which of the following is true?
    • A. Train A has a greater acceleration than train B, reaches a greater velocity and goes a greater distance.
    • B. Train A has a the same acceleration as train B, but accelerates longer, reaches a greater velocity and goes a greater distance.
    • C. Train A has a the same acceleration as train B, achieves the same velocity, but travels longer and goes a greater distance.
    • D. Train A starts out with a higher velocity than train B.
    • E. Both trains travel the same distance.
