Answer to Question 1

Answer: B

Answer to Question 2

Answer: In accord with Newton's first law, since in both cases there is no horizontal force on the dropped pencil, no change of velocity occurs horizontally. The dropped pencil in the moving bus simply keeps up with you as you move, not changing its velocity in the horizontal direction.
