For Line B on the velocity versus time graph, which slopes upward from the origin to the upper right corner, the velocity of the object is increasing over time. Since velocity is increasing, the position of the object is also increasing because a positive velocity indicates that the object is moving in the positive direction.
Acceleration represents the rate of change of velocity. Since the velocity of the object is continuously increasing in a linear manner (as indicated by the straight line), we can infer that the acceleration is also positive.
Therefore, the correct response is:
velocity, position, and acceleration.
