The graph below shows how the speed of a bus change during part of a journey. Use this graph to answer questions 3-5 3. In Segment B-C, the bus is

_ (accelerating;

decelerating; at rest; at constant speed)

Why?

4. In Segment C-D, the bus is

_ (accelerating;

decelerating; at rest; at constant speed)

Why?

5. Which Segment(s) is accelerating? How

do you know?

O to A and D to E are accelorating.

Explanation:

You can tell because the graphed points have positive slopes in these locations.

50 inches should be the resultant vector
