Answer

Explanation:

Step1: Recall acceleration formula

The formula for acceleration is $a=\frac{v - u}{t}$, where $v$ is final - velocity, $u$ is initial velocity, and $t$ is time. Since they start from rest, $u = 0\ m/s$, so $a=\frac{v}{t}$.

Step2: Calculate Xander's acceleration

For Xander, $v = 4.5\ m/s$ and $t = 3.5\ s$. Then $a_{Xander}=\frac{4.5}{3.5}\approx1.29\ m/s^{2}$.

Step3: Calculate Finley's acceleration

For Finley, $v = 3.6\ m/s$ and $t = 4.2\ s$. Then $a_{Finley}=\frac{3.6}{4.2}\approx0.86\ m/s^{2}$.

Step4: Calculate Max's acceleration

For Max, $v = 7.3\ m/s$ and $t = 1.2\ s$. Then $a_{Max}=\frac{7.3}{1.2}\approx6.08\ m/s^{2}$.

Step5: Compare accelerations

Comparing the values: $a_{Finley}<a_{Xander}<a_{Max}$.

Answer:

Finley → Xander → Max
