The average velocity of the object, given the data is 1.25 m/s
What is velocity?
Velocity is simply defined as the rate of change of displacement with time. Mathematically, it can be expressed as:
Velocity = displacement / time
What is average velocity
This is simply defined as total displacement travelled divide by the total time
Average velocity = Total displacement / total time
How to determine the total displacement
From the question given above, we were told that the object moved from x = 15 m to x = 165 m. Thus, the displacement at this point is
Displacement = 165 - 15 = 150 m
Also, we were told that the object moved back to x = 25 m.
Thus, the total displacement will be
Total displacement = 150 - 25 = 125 m
How to determine the average velocity
- Total displacement = 125 m
- Total time = 100 s
- Average velocity =?
Average velocity = Total displacement / total time
Average velocity = 125 / 100
Average velocity = 1.25 m/s
