Without the actual graph to analyze the person's motion, I cannot definitively determine which statement is correct. However, I can help you understand how to compare motion based on typical graph features:
-
Speed: If the slope of the graph (which usually represents speed) is steeper in one section than another, that indicates a higher speed. A flat line indicates no movement.
-
Direction: If the graph plots against time in a way that shows a change in the sign of the value (for example, moving from positive to negative), that would indicate a change in direction.
-
Acceleration: If the slope of the speed line is changing (steeper slopes indicate increasing speed), then acceleration is either increasing (speeding up) or decreasing (slowing down).
Given these concepts, here’s how to evaluate the statements:
- If in the first 10 minutes the motion is represented as a steeper slope and changes direction, you might conclude that he is going faster and in a different direction.
- If he starts slow and ends up speeding up during the first 10 minutes, and then slows down during the last 10 minutes, that fits one of the provided statements.
Please refer back to the graph with these points in mind to determine which statement is accurate.
