Question

A skateboarder rolls along the sidewalk with a constant velocity for 60 seconds, moving away from the reference point. Which of the following statements is true?

A) The skateboarder's velocity is increasing.
B) The skateboarder's velocity is decreasing.
C) The skateboarder's velocity remains constant.
D) The skateboarder's velocity cannot be determined without additional information.

Answer 1

The correct answer C) The skateboarder's velocity remains constant. The skateboarder's velocity remains constant as there is no change in speed or direction during the 60 seconds of motion.

Step-by-step explanation:

The correct answer is C) The skateboarder's velocity remains constant. If a skateboarder is rolling along the sidewalk with a constant velocity for 60 seconds and moving away from the reference point, it means that there is no change in the speed or direction of the skateboarder's motion during this time period. There is no acceleration, and thus the velocity does not change during the 60 seconds. Therefore, the skateboarder is neither accelerating nor decelerating.
