Question

xander reached a final velocity of 4.5 m/s in 3.5 seconds. finley reached a final velocity of 3.6 m/s in 4.2 seconds. max reached a final velocity of 7.3 m/s in 1.2 seconds. they all started at the same location from rest. which lists them from least to most acceleration?

• max → finley → xander
• max → xander → finley
• xander → finley → max
• finley → xander → max

Explanation:

Step1: Define acceleration formula

Acceleration $a = \frac{v_f - v_i}{t}$, where $v_i=0$ (started from rest), so $a = \frac{v_f}{t}$.

Step2: Calculate Xander's acceleration

$a_X = \frac{4.5}{3.5} \approx 1.29 \, \text{m/s}^2$

Step3: Calculate Finley's acceleration

$a_F = \frac{3.6}{4.2} \approx 0.86 \, \text{m/s}^2$

Step4: Calculate Max's acceleration

$a_M = \frac{7.3}{1.2} \approx 6.08 \, \text{m/s}^2$

Step5: Order from least to most

Compare values: $0.86 < 1.29 < 6.08$, so Finley → Xander → Max.

Answer:

Finley → Xander → Max
