To accurately analyze the motion of the person based on the graph (which I cannot see), I can guide you on how to interpret the choices based on typical motion graph characteristics.
-
Acceleration Changes: If the slope of the position versus time graph is changing, that's an indication of acceleration. A steeper slope means faster speed, while a flat section indicates no movement or constant speed.
-
Direction of Motion: This can be assessed based on whether the position graph is increasing or decreasing. An increasing position typically indicates motion in one direction (e.g., forward), while a decreasing position indicates motion in the opposite direction (e.g., backward).
-
Speeding Up vs. Slowing Down: If the slope of the graph increases, the object is speeding up. If the slope decreases, the object is slowing down.
Given these points, if you observe that the person’s speed or direction changes significantly between the first and last 10 minutes, you can choose the most appropriate statement from the options you provided.
For example:
- If in the first 10 minutes the slope is increasing (moving forward) and in the last 10 minutes the slope decreases or becomes negative (moving backward or slowing), the statement "He is speeding up during the first 10 minutes and slowing down during the last 10 minutes" might be correct.
- Conversely, if the direction changes but speed remains constant, the statement regarding "going faster in a different direction" would be relevant.
Please refer to the graph and check these characteristics to determine the correct answer.
