Question

detector. use the graph to answer the question.
position vs. time
how is an object moving in relation to the origin in the red portion of the graph?
it is moving toward the point of origin.
it is moving away from the point of origin.
it is not moving during this time frame.

Explanation:

In a position - time graph, the position of the object relative to the origin (position = 0) is shown on the y - axis. For the red portion of the graph, we observe the change in position as time increases. The origin is at position 0. As time progresses in the red part, the position of the object is increasing (moving from lower y - values towards higher y - values, getting further from y = 0). Wait, no, wait. Wait, the first part of the blue graph: at t = 0, position is 40m. Then it goes down to 10m at t = 3s (approx). Then the red graph starts: at t = 3s, position is 10m, then at t = 4s, 15m; t = 5s, 20m; t = 6s, 25m; t = 7s, 30m. So as time increases in the red portion, the position is increasing (moving from 10m to 30m), which means it is moving away from the origin (since origin is 0, and 10 to 30 is further from 0). Wait, no, wait the options: the first option is "It is moving toward the point of origin" (origin is 0, so moving towards 0 would be position decreasing), the second is "moving away" (position increasing), third is "not moving". In the red portion, the position is increasing (from 10m to 30m as time goes from 3s to 7s), so it is moving away from the origin. Wait, but wait, maybe I misread. Wait the red dots: at t = 3 (or around 3) position is 10, then t = 4:15, t = 5:20, t = 6:25, t = 7:30. So position is increasing with time, so distance from origin (which is at 0) is increasing. So the object is moving away from the origin.

Answer:

B. It is moving away from the point of origin. (Assuming the options are labeled as A: It is moving toward the point of origin, B: It is moving away from the point of origin, C: It is not moving during this time frame)
