To determine if either object has a constant velocity, we can analyze their position-time graphs. An object has a constant velocity if its position changes linearly with time, which would be represented by a straight line on the graph.
- If the graph for object C is a straight line, then object C has a constant velocity.
- If the graph for object D is a straight line, then object D has a constant velocity.
If both graphs are straight lines, then both have constant velocities. If neither graph is a straight line, then neither object has a constant velocity.
Since I cannot directly view the graphs, I cannot confirm which response is correct without that information. Based on the options you've given, please choose the appropriate response based on the characteristics of the graphs for object C and object D.
