Question

7 multiple choice 1 point what is happening at 4 seconds? position vs. time 10 8 6 4 2 0 0 1 2 3 4 5 6 7 8 9 10 time (seconds) image.png the objects are crashing into one another at 4 meters. the objects are merely passing each other at 4 meters. the objects are stopping to talk to one another at 4 meters. the objects are changing directions at 4 meters.

Explanation:

A position-time graph shows an object's position over time. At 4 seconds, the two lines intersect, meaning both objects are at the 4-meter position simultaneously. The lines have constant slopes (so constant velocities, no direction change), and this represents the objects passing each other at that position. The other options are incorrect: "crashing" is not indicated (the graph only shows position, not collision), "stopping to talk" is a non-scientific interpretation, and neither object changes direction (slopes don't switch sign).

Answer:

The objects are merely passing each other at 4 meters.
