Question

5. The graph above shows displacement versus time. What is the average velocity for line A?

6. The graph above shows displacement versus time. What is the average velocity for line B?
7. The graph above shows displacement versus time. What is the average velocity for line C?

Answer 1

The average velocities for the various lines shown in the graph are:

• 3.33 m/s for line A
• 1.12 m/s for line B
• 0.28 m/s for line C

How to calculate the average velocity for each lines?

The average velocities for the various lines can be calculated as follow:

For line A:

• Total displacement = 10 m
• Total time = 3 s
• Average velocity for A =?

Average velocity for A = Total displacement / Total time

= 10 / 3

= 3.33 m/s

For line B:

• Total displacement = 9.5 m
• Total time = 8.5 s
• Average velocity for B =?

Average velocity for B = Total displacement / Total time

= 9.5 / 8.5

= 1.12 m/s

For line C:

• Total displacement = 2.5 m
• Total time = 9 s
• Average velocity for C =?

Average velocity for C = Total displacement / Total time

= 2.5 / 9

= 0.28 m/s
