Answer 2

Hint:
Think of position (y-axis) as distance.
Imagine you're bouncing a ball against a wall.
Say, y=0 is where your are, and y=4 is the wall.
Try to describe the motion of the ball with respect to time.

Answer 3

The time it takes for the ball to reach 4 meters is 3 seconds.

Answer 4

Answer 5

It moves away from its starting point at a constant speed for the first 2 seconds.

What is it doing for the next second? Staying still? moving away or towards?

For the final four seconds - is it moving towards or away from its starting point?

Answer 6

Idk which question you're answering. Be specific.

Answer 7

in the next second it is moving away from the starting point.
in the final four seconds it's moving away from the starting point.

Answer 8

in the final four seconds it comes to original position.

Answer 9

Those are both incorrect.

If the line is moving *upward*, then it is moving away from starting point

If the line is moving *downward*, then it is moving toward the starting point

If the line is moving *neither up or down*, then it is sitting still

Answer 10

positive slope = moving away

negative slope = moving towards

zero slope = sitting still

Answer 11

alright

Answer 12

So now using that, describe the graph.

Answer 13

It moves away from it's starting point at 2 seconds. In the next second, it moves toward the starting point. Lastly, in the final 4 seconds it moves towards the starting point.

Answer 14

Not quite.

It moves away from it's starting point *for the first* 2 seconds.

***In the next second, it moves toward the starting point.*** No. What is the slope of that section of the graph?

Lastly, in the final 4 seconds it moves towards the starting point.

Answer 15

it stays still

Answer 16

Good
