<span>Is more than one displacement possible?
No, displacement only considers the initial and final position.
Is more than one average velocity possible?
No, the average velocity is defined as displacement per time and since there is only one displacement possible, there is only one average velocity possible as well.
Is more than one average speed possible?
Yes, the average speed considers the total distance traveled and this distance may not be the same as the total displacement.

Answer:
d, the awnser all of the above
Answer;
A.It’s not moving.
Explanation;
Position-Time graphs display the motion of a object by showing the changes of velocity with respect to time.
The motion of a car on a position-time graph that is represented with a horizontal line indicates that the car has stopped moving.
A straight line with a positive slope indicates that the car is moving at a constant velocity, and thus the slope is constant. On the other hand, a curve with a changing slope, shows that the velocity is changing.
Answer:
a) Δx ≈ 8.4 m
b) v ≈ 6.1 m/s
Explanation:
Given:
v₀ = 1.5 m/s
a = 2.1 m/s²
t = 2.2 s
a) Find: Δx
Δx = v₀ t + ½ at²
Δx = (1.5 m/s) (2.2 s) + ½ (2.1 m/s²) (2.2 s)²
Δx ≈ 8.4 m
b) Find: v
v = at + v₀
v = (2.1 m/s²) (2.2 s) + (1.5 m/s)
v ≈ 6.1 m/s
