The correct option is:
interval AB → constant speed
interval BC → decreasing speed
interval CD → constant speed
interval DE → increasing speed
The correct option is: interval AB → constant speed, interval BC → decreasing speed, interval CD → constant speed, interval DE → increasing speed.
To determine the correct motion of the object for each time interval, we need to analyze the given graph.
The graph shows the object's distance traveled over time intervals. By examining the graph, we can observe how the distance changes over each interval.
Let's consider each interval one by one:
- Interval AB: In this interval, the graph shows a straight, horizontal line, indicating that the object's distance remains constant over time. Therefore, the correct motion for interval AB is constant speed.
- Interval BC: In this interval, the graph shows a downward slope, indicating that the distance traveled is decreasing over time. Therefore, the correct motion for interval BC is decreasing speed.
- Interval CD: In this interval, the graph shows another straight, horizontal line, similar to interval AB. This indicates that the object's distance remains constant once again. Hence, the correct motion for interval CD is constant speed.
- Interval DE: In this interval, the graph shows an upward slope, indicating that the distance traveled is increasing over time. Therefore, the correct motion for interval DE is increasing speed.
Based on the above analysis, the option that correctly lists the motion of the object for each time interval is:
Interval AB → constant speed
Interval BC → decreasing speed
Interval CD → constant speed
Interval DE → increasing speed
