Answer:
0.11 m/s and 0.28 m/s
Explanation:
Average velocity is defined as the ratio of total displacement covered to the total time taken.
For first 0.25 m
Total displacement = 0.25 m
Total time taken = 2.23 second
[tex]Avearge velocity = \frac{0.25}{2.23}[/tex]
Average velocity = 0.11 m/s
For second 0.25 m
Total displacement = 0.50 - 0.25 = 0.25 m
Total time = 3.13 - 2.23 = 0.9 second
[tex]Avearge velocity = \frac{0.25}{0.9}[/tex]
Average velocity = 0.28 m/s
