HURRY !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

Xander was traveling at a final velocity of 4.5 m/s for 3.5 seconds. Finley was traveling at a final velocity of 3.6 m/s for 4.2 seconds. Max was traveling at a final velocity of 7.3 m/s for 1.2 seconds. They all started from the same location.
Which lists them from least to most acceleration?
A. Max → Finley → Xander
B. Max → Xander → Finley
C. Xander → Finley → Max
D. Finley → Xander → Max

The answer is D. Finley → Xander → Max because Finley was the slowest and xavier was the fastest

Answer: D. Finley → Xander → Max

Step-by-step explanation:

Given

Xander , Finley and Max all started from the same location . So all are having initial velocity zero .

Final velocities are


V_(xander)=4.5 (m)/(s) ,V_(finley)=3.6 (m)/(s), V_(max)=7.3(m)/(s)

Now , Acceleration ,
a=(V_(final)-V_(initial))/(t)

=> Acceleration of Xander ,
a_(xander)=(4.5)/(3.5)(m)/(s^(2)) = 1.29 (m)/(s^(2))

Acceleration of Finley ,
a_(finley)=(3.6)/(4.2)(m)/(s^(2)) = 0.857 (m)/(s^(2))

Acceleration of Max ,
a_(max)=(7.3)/(1.2)(m)/(s^(2)) = 6.08 (m)/(s^(2))

Thus order of their acceleration from least to most is Finley → Xander → Max

=> correct option is D. Finley → Xander → Max
