To determine which quantities are increasing for the object represented by Line B, we need to analyze the graph in detail. Since I cannot see the graph, I will outline how to interpret it based on the given options.
-
Velocity: If the slope of the position-time graph (Line B) is increasing, it indicates that the object's velocity is increasing.
-
Position: If the object's position is increasing over time (the line is going upwards), then the position is increasing.
-
Acceleration: Acceleration can be inferred from the change in velocity. If the graph shows that the velocity is increasing over time, acceleration is positive.
Based on these interpretations, here's how the responses can be categorized:
- If Line B has a positive slope (indicating both position and velocity are increasing), check if the increase in velocity is accelerating as well.
- If Line B is curved upwards (in the graph), then both position and velocity are increasing, and if the slope is increasing, acceleration is also increasing.
- If it's a straight increasing line, then velocity is increasing but could be constant acceleration.
Based on this analysis, review the graph again. If:
- Velocity and position are rising; acceleration is positive: The answer is velocity, position, and acceleration.
- Only velocity and position are increasing: The answer is velocity and position.
- Only velocity is increasing: The answer is velocity only.
Please apply these interpretations to the actual graph to select the appropriate answer.
