Question

13.) write everything you know from the distance vs. time graph below: (minimum of 5, 6 - 10 are extra credit!) part description 1.) 2.) 3.) 4.) 5.) 6.) 7.) 8.) 9.) 10.)

Explanation:

1. In Part A, the distance (x) increases as time (t) increases from 0 - 2, indicating motion away from the starting - point.
2. The slope of the line in Part A represents a constant positive velocity.
3. At the end of Part A (t = 2), the object has reached a maximum distance of 4 units from the starting - point.
4. In Part B, the distance decreases as time increases from 2 - 3, indicating motion towards the starting - point.
5. The slope of the line in Part B represents a constant negative velocity.
6. In Part C, from t = 3 - 4, the distance remains constant at 2 units, indicating the object is stationary.
7. The slope of the line in Part C is 0, which means zero velocity.
8. In Part D, from t = 4 - 8, the distance decreases steadily as time increases, indicating motion towards the starting - point.
9. The slope of the line in Part D represents a constant negative velocity.
10. At t = 8, the object returns to the starting - point (x = 0).

Answer:

1. Part A: Object moves away from starting - point with constant positive velocity.
2. Part B: Object moves towards starting - point with constant negative velocity.
3. Part C: Object is stationary.
4. Part D: Object moves towards starting - point with constant negative velocity.
5. Maximum distance from starting - point is 4 units at t = 2.
6. Object is at a distance of 2 units from starting - point from t = 3 - 4.
7. Slope of Part A is positive, representing positive velocity.
8. Slope of Part B is negative, representing negative velocity.
9. Slope of Part C is 0, representing zero velocity.
10. Slope of Part D is negative, representing negative velocity.
