On this graph, what is the displacement from 0s to 8s? // A. 0.6 m B. 5.0 m C. 2.0 m D. 10.0 m ... I think it's B, if you subtract the final placement and the initial placement. I have a photo to help. Also, what would the instantaneous velocity be here?
The slope of the line at any point in time?
The difference between the final and initial displacement?
The displacement divided by the time interval?
The difference between the final and initial time?

I agree on B
inst. vel. is the slope of the line at a point.
its b
To find the displacement from 0s to 8s, you can indeed subtract the final position from the initial position. If you have a photo of the graph, you can use it to identify the positions at 0s and 8s and calculate the difference.
Now, let's go through each part of your question:
1. Displacement from 0s to 8s: To determine the displacement, you can find the difference between the final and initial positions. From your options, you can select the correct answer by subtracting the initial position from the final position.
2. Instantaneous velocity: To find the instantaneous velocity, you need the slope of the graph at a specific point in time. On a distance-time graph, the slope represents the velocity. You can identify a specific point on the graph, draw a tangent line, and find the slope of that line. The slope will give you the instantaneous velocity at that point.
3. Slope of the line at any point in time: As mentioned above, the slope of the line on a distance-time graph represents the velocity. To find the slope at any point, you need to draw a tangent line at that specific point and calculate its slope using the rise over run formula (change in distance divided by change in time).
4. Difference between final and initial displacement: To find the difference between the final and initial displacement, you can subtract the initial displacement from the final displacement. It is the same concept as finding the displacement from 0s to 8s.
5. Displacement divided by the time interval: To calculate the displacement divided by the time interval, you would divide the displacement by the corresponding time difference. This would give you average velocity over that time interval.
6. Difference between final and initial time: To find the difference between the final and initial time, you simply subtract the initial time from the final time.
By understanding the concepts behind these questions and using the given graph, you should be able to determine the displacement and instantaneous velocity accurately.
