### Velocity vs Time #### Graph Description: The graph titled "Velocity vs Time" displays a line graph with the x-axis representing time in seconds (s) ranging from 0 to 5, and the y-axis representing velocity in meters per second (m/s) ranging from -30.00 to 30.00. The graph shows a downward-sloping line, plotted with red square markers, indicating a decrease in velocity over time. #### Analysis: - At 0 seconds, the velocity is slightly above 15 m/s. - By 2 seconds, the velocity decreases to approximately 0 m/s. - The velocity becomes negative as time approaches 3 to 5 seconds, reaching around -15 m/s at 4 seconds. #### Question: "According to the graph above, what does this object do at the 2 second mark?" ##### Options: - o turns right - o decreases its acceleration - o comes to a complete stop and changes direction - o turns left Students are encouraged to analyze the graph carefully to determine the correct answer based on the interpretation of velocity changes over time.

Expert Solution
Step 1

In the graph, the velocity of the body decreases from 20m/s to -20m/s through zero velocity.

If the sign of velocity changed means, the direction of motion of body changed. The velocity comes to zero means, the body comes to a complete stop.

Hence the third option, the body comes to a complete stop and changes direction is correct.
