Question

what is modeled by the graph segment between b and c?

• the height is remaining constant over time.
• the time is remaining constant while the height changes.
• the height is increasing.
• the height is decreasing.

Explanation:

Identify the variables on the axes

The vertical axis (\(y\)-axis) represents "Height" and the horizontal axis (\(x\)-axis) represents "Time".

Analyze the segment between B and C

The graph segment between point B and point C is a horizontal line segment.

Determine the physical meaning of a horizontal segment

A horizontal line on a height-versus-time graph indicates that as time increases, the height value does not change. Therefore, the height remains constant.

Answer:

• The height is remaining constant over time. (Correct answer)
• The time is remaining constant while the height changes.
• The height is increasing.
• The height is decreasing.
