Question

student investigates the motion of a toy vehicle. The student graphs 40 seconds of data from the investigation.



Which statement best describes the motion of the toy vehicle during the first 30 seconds of the investigation?

Responses
A The vehicle was traveling at a constant speed.The vehicle was traveling at a constant speed.
B The vehicle was speeding up (accelerating) at a constant rate.The vehicle was speeding up (accelerating) at a constant rate.
C The speed of the vehicle was increasing.The speed of the vehicle was increasing.
D The vehicle was slowing down (decelerating) at a constant rate.

To accurately determine the best description of the motion of the toy vehicle during the first 30 seconds, we would typically need to analyze the graph that represents the data. However, since I cannot see the graph, I'll guide you on how to interpret the options based on common scenarios in motion graphs:

1. **Constant Speed:** If the graph shows a straight, horizontal line during the first 30 seconds, then option A ("The vehicle was traveling at a constant speed.") would be correct.

2. **Accelerating at a Constant Rate:** If the graph shows a straight line that slopes upward (indicating an increase in speed) during the first 30 seconds, then option B ("The vehicle was speeding up (accelerating) at a constant rate.") would apply.

3. **Increasing Speed:** If the vehicle's speed is increasing but not at a constant rate—maybe the slope is changing—option C ("The speed of the vehicle was increasing.") could be accurate, but it’s less specific.

4. **Slowing Down:** If the graph shows a straight line that slopes downward (indicating a decrease in speed) during the first 30 seconds, then option D ("The vehicle was slowing down (decelerating) at a constant rate.") would be the correct choice.

To select the best option among the four, review the graph closely for the type of line (straight or curved, upward or downward slopes) to determine the vehicle's motion clearly. Provide additional data or describe the graph if you need a more precise answer.
