Answer explanation

If the person is at rest, their position remains the same over time.

What will the slope look like if the object were in a positive constant motion?

• 

Answer explanation

If they were moving in a positive velocity, it would be moving up along the y axis.

What will the slope look like if the object were in a negative constant motion?

Answer explanation

a negative slope would indicate that the person/object is moving back towards its originial position if Xi=0.

• From B to C

• From C to D

• From D to E

• From B to C

• From C to D

• From D to E

8.) From 9 to 12 seconds the average velocity of the person was ...

• 1 m/s

• -1 m/s

• 3 m/s

• -3 m/s

Answer explanation

xf-xi= (-8)-(-5)=-3m,

tf-ti= (12-9) = 3sec

so -3/3 = -1 m/s

From 5 to 6 seconds the average velocity of the person was ...

• 1 m/s

• -1 m/s

• 3 m/s

• -3 m/s

• 0 m/s

Answer explanation

xf-xi= (25)-(25)=0m,

They did not move, so they are at rest
