Final answer:
The velocity vs. time graph shows an object that starts from rest, speeds up, and eventually stops. This is interpreted by a horizontal line initially at zero, followed by a line with a positive slope, and finally returning to a horizontal line at zero.
Step-by-step explanation:
The question pertains to the interpretation of a velocity vs. time graph for an object in motion. A velocity vs. time graph provides information on how an object's speed changes over time, which directly relates to the object's acceleration. Constant velocity is represented by a horizontal line on such a graph, while changes in velocity (speeding up or slowing down) are shown by lines with a positive or negative slope respectively. A horizontal line at a velocity greater than zero indicates movement at constant speed, a line with a positive slope indicates acceleration, and a return to zero velocity indicates the object has stopped. The graph described in the question seems to reflect an object which starts from rest, increases its velocity (speeds up), and then returns to a velocity of zero (stops).
