Both objects have a constant velocity.
Both objects have a constant velocity.

Neither object has a constant velocity.

Answer 1

To determine whether either object has a constant velocity based on position-time graphs, you would look for straight lines on the graph. A straight line indicates that the position is changing at a uniform rate over time, which corresponds to constant velocity.

• If object C's graph is a straight line, then it has a constant velocity.
• If object D's graph is also a straight line, then it too has a constant velocity.

If the graph for either object is curved, then that indicates changing velocity, meaning neither object has a constant velocity.

Since I cannot view the graphs, I cannot provide a definitive answer. However, you can assess the graphs based on the criteria mentioned above. The response can be one of the following:

• If only object C's graph is a straight line: "Only object C has a constant velocity."
• If only object D's graph is a straight line: "Only object D has a constant velocity."
• If both graphs are straight lines: "Both objects have a constant velocity."
• If neither graph is a straight line: "Neither object has a constant velocity."
