Use the graph to the right for the next three questions.

42.  Which segment has a constant reverse velocity?

43.  Which segment has the object not moving?

44.  Which segment represents acceleration?

    

 

42. A constant velocity has a downward sloped line in the graph of displacement vs time.  The Segment DE is the Correct Answer.
     
43. If the object is not moving, its displacement is constant with time. This will show up as a horizontal line in the graph.  The Segment CD is the Correct Answer.
     
44. Acceleration shows up as an upward curved line.   Deceleration shows up as a downward curved line.  Deceleration is a negative acceleration.  The Segment BC is the Correct Answer.
