"Describe the motion (including direction) for each of the time segments listed.

[(Example) 20-24 seconds walking slowly back to origin 0-2 seconds]
A) 4-10 seconds _____________________
B) 12-16 seconds _____________________
C) 16-18 seconds _____________________
D)18-20 seconds _____________________
How fast is the object traveling from 16-18 seconds? _____________________"

1. During the time segment 4-10 seconds, assuming an initial point of "0," the object is:
- A) Moving toward the initial point at a moderate speed.
- B) Moving away from the initial point at a moderate speed.
- C) Stationary.
- D) Not enough information to determine.

2. During the time segment 12-16 seconds, assuming an initial point of "0," the object is:
- A) Moving toward the initial point at a moderate speed.
- B) Moving away from the initial point at a moderate speed.
- C) Stationary.
- D) Not enough information to determine.

3. During the time segment 16-18 seconds, assuming an initial point of "0," the object is:
- A) Moving away from the initial point at a faster speed.
- B) Moving toward the initial point at a faster speed.
- C) Stationary.
- D) Not enough information to determine.

4. During the time segment 18-20 seconds, assuming an initial point of "0," the object is:
- A) Moving away from the initial point at a slower speed.
- B) Moving toward the initial point at a slower speed.
- C) Stationary.
- D) Not enough information to determine.


Please note that these questions and answers are based on the assumption of an initial point at "0."

Final answer:

The object is moving toward the initial point at a moderate speed from 4-10 seconds, is stationary from 12-16 seconds, and is moving away from the initial point at a faster speed from 16-18 seconds. From 18-20 seconds, the object is moving away from the initial point at a slower speed. From 16-18 seconds, the object is traveling at a faster speed.

Step-by-step explanation:

For the time segment 4-10 seconds, the object is moving toward the initial point at a moderate speed. This is because the position vs. time graph shows a positive slope, indicating a positive velocity.

For the time segment 12-16 seconds, the object is stationary. This is because the position vs. time graph has a flat line, indicating that the object is not changing its position.

For the time segment 16-18 seconds, the object is moving away from the initial point at a faster speed. This is because the position vs. time graph shows a negative slope, indicating a negative velocity.

For the time segment 18-20 seconds, the object is moving away from the initial point at a slower speed. This is because the position vs. time graph has a steep negative slope, indicating a slower negative velocity.

The object is traveling at a faster speed from 16-18 seconds. This is because the position vs. time graph shows a steep negative slope, indicating a faster negative velocity.
