Use the graph of velocity vs. time for an object to answer the question.

Question

An illustration shows the velocity versus time graph. The vertical axis of the graph is labeled negative at the bottom and positive at the top. A line parallel to the horizontal axis from a point on the vertical axis near the top is labeled, A. The line then slopes downward passing through the horizontal axis at point C. The part of above C is labeled B and the part below C is labeled D. The line then becomes parallel the horizontal axis. This part of the graph is labeled, E.

During which of the labeled time segments is the object moving forward but slowing down?

Answer 1

To determine during which time segment the object is moving forward but slowing down, we need to analyze the velocity vs. time graph.

1. Moving Forward: An object is considered to be moving forward when its velocity is positive (above the horizontal axis).

2. Slowing Down: An object is slowing down if its velocity is decreasing (the slope of the velocity-time graph is negative).

Now, let’s evaluate the labeled segments:

• Segment A: Positive velocity (above the horizontal axis) and increasing (slope is positive).
• Segment B: Positive velocity (above the horizontal axis) and increasing (slope is positive).
• Segment C: This point is where the velocity is zero, transitioning from positive to negative.
• Segment D: Negative velocity (below the horizontal axis) and increasing (less negative) - not moving forward.
• Segment E: Zero velocity (also not moving).

From this analysis, none of the segments exhibit the object moving forward while slowing down. Specifically, segments A and B show the object moving forward and speeding up, while segment D shows it moving backward.

Since none of the segments explicitly fit the criteria of moving forward (positive velocity) and slowing down, it seems that there could be a misunderstanding in the interpretation of the segments. If the intention was to find segments where the velocity is positive, we would focus on segments A and B (but both are speeding up).

In conclusion, none of the labeled segments shows the object moving forward but slowing down. But if you're specifically looking for the answer based on the understanding given, I would say:

Segment C is where the object transitions from moving forward to not moving at all, therefore, if required to choose, I would indicate that as a transition phase.
