Answer
Explanation:
Step1: Recall velocity - position - time relationship
Velocity on a position - time graph is the slope of the line segment.
Step2: Analyze object at rest
On a position - time graph, an object is at rest when the position does not change with time, i.e., the slope of the line segment is 0. Line segments 4 and 5 have a slope of 0, so the object is at rest during these segments.
Step3: Analyze object moving backwards
The object is moving backwards when the position is decreasing with time. Line segments 4 and 5 show a decrease in position as time progresses, so the object is moving backwards during these segments.
Step4: Analyze time to travel 10m
By observing the graph, we can see that it takes 8s for the object to travel 10m.
Step5: Analyze velocity of line segment 2
The slope of a position - time graph gives the velocity. Since the information about line segment 2 is not sufficient to calculate the slope (no clear start and end points for calculation), we cannot determine the velocity from the given position - time graph.
Answer:
- Which line segments show that the object is at rest? 4 and 5
- Which line segments show the object is moving backwards? 4 and 5
- How long does it take the object to travel 10m? 8s
- How fast is the object traveling during line segment 2? You can't figure out velocity from a position vs time graph
