A2L Item 259
- Description: Identify the location of an object at a specific time given a plot of velocity versus time.
- Goal: Interrelate representations of kinematical quantities
- Source: CT151.2-8
- Keywords: Displacement, Graphing, Mechanics, Velocity
The question for students:
An object’s motion is described by the graph above. The position of the object at t = 9 seconds is most nearly…
- 0 meters
- 200 meters
- 300 meters
- 400 meters
- 500 meters
- Cannot be determined
Commentary for teachers:
Answer
(6) This problem is primarily to determine if students appreciate the information available from a graph. Many students will determine the displacement forgetting that the initial position is unknown.
