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

Question

the graph has a straight line labeled A and a line going down labeled B, at the start of the line going down, C, at the middle, and D at the end, and a straight line at the bottom labeled E

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

Answer 1

To determine during which labeled time segments the object is moving forward but slowing down based on a velocity vs. time graph, we need to analyze the signs of the velocity and the slope of the line (which represents acceleration).

1. Moving Forward: The object is moving forward when the velocity is positive (above the time axis).
2. Slowing Down: The object is slowing down when the velocity is positive but decreasing (the slope of the line is negative), which means the line slopes downward.

From the description:

• Segment A: If this is above the time axis with a positive slope, the object is speeding up.
• Segment B: If the velocity is positive but decreasing (a downward slope), the object is moving forward but slowing down.
• Segment C: If this is the start of a downward slope from a positive velocity, this still indicates slowing down.
• Segment D: Similar to C, but it is important to note if it crosses the time axis.
• Segment E: This is below the time axis, so the object is not moving forward.

Based on this analysis, since the object is moving forward but slowing down only during the segments where the velocity is positive and the slope is negative, it can be concluded that the segments where this occurs are:

• Segment B (if it's negative).
• Segments C and D may also indicate the phenomenon you are describing if the velocity is still positive at the beginning of these segments.

Therefore, the answer is most likely Segment B (where the object is moving forward and slowing down). If Segments C and D do not have a positive velocity when they start, then only Segment B is accurate.
