Constant Velocity: Position-Time Graphs

Directions: On this worksheet you will review some of the properties of position-time graphs when the object is moving at a "constant velocity."

Question 1  The y-axis, representing position, is scaled so that each square (vertical division) represents 11 meters. The x-axis is scaled so that each square represents 1 second.


7,11,17 seconds

What was the cart's instantaneous speed at 3 seconds?
Question 2  What was the cart's average speed during the first 9.2 seconds?
Question 3  Where was the cart located at exactly 12 seconds?
Question 4  What was the magnitude of the cart's instantaneous velocity at 7 seconds?
Question 5  What was the cart's average velocity between 7 and 12 seconds?
Question 6  What was the cart's average speed for the entire 17 seconds?
