The fact that V(t) is zero indicates that Jack's bicycle has come to a stop and is not in motion at that particular time.
The significance of V(t) having a value of zero in the given table is that it indicates that Jack's bicycle will not be moving at that particular time.
When the velocity (V) is zero, it means that there is no change in Jack's position or speed. In other words, he has come to a stop. This can be seen at t = 20 seconds in the table, where the velocity is 0.5 m/s. At this point, Jack's bicycle is not in motion and he has ceased pedaling.
Option B) "Jack's bicycle will not be moving" best describes the significance of V(t) having a value of zero.
It is important to note that V(t) being zero does not provide any information about how long Jack has coasted (option A), whether Jack is pedaling again (option C), or how far he has traveled (option D).
