Answer

Explanation:

Step1: Recall the formula for change in velocity

The formula for change in velocity $\Delta v=a\times t$, where $a$ is acceleration and $t$ is time.

Step2: Calculate change in velocity for Kira

For Kira, $a = 5.2\ m/s^{2}$ and $t=6.9\ s$. So $\Delta v_{Kira}=5.2\times6.9 = 35.88\ m/s$.

Step3: Calculate change in velocity for Dustin

For Dustin, $a = 8.3\ m/s^{2}$ and $t = 3\ s$. So $\Delta v_{Dustin}=8.3\times3=24.9\ m/s$.

Step4: Calculate change in velocity for Diego

For Diego, $a = 6.5\ m/s^{2}$ and $t = 4.2\ s$. So $\Delta v_{Diego}=6.5\times4.2 = 27.3\ m/s$.

Step5: Compare the values

$35.88>27.3>24.9$, so $\Delta v_{Kira}>\Delta v_{Diego}>\Delta v_{Dustin}$.

Answer:

Kira - Diego - Dustin
