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?

AMax → Finley → Xander
BMax → Xander → Finley
CXander → Finley → Max
DFinley → Xander → Max

Answer:

The correct answer is option C.

Explanation:

Acceleration is defined as rate of change of velocity with respect to time.

\(Acceleration =\frac{Velocity}{Time}\)

Acceleration of Xander =\(a_x\)

Velocity of Xander during the interval of 3.5 seconds = 4.5 m./s

\(a_x=\frac{3.5 m/s}{4.5 s}=0.7777 m/s^2\)

Acceleration of Finley=\(a_f\)

Velocity of Finley during the interval of 4.2 seconds = 3.6 m./s

\(a_f=\frac{3.6 m/s}{4.2 s}=0.8571 m/s^2\)

Acceleration of Max=\(a_m\)

Velocity of Max during the interval of 1.2 seconds = 7.3 m./s

\(a_f=\frac{7.3 m/s}{1.2 s}=6.0833 m/s^2\)

\(a_x

Xander → Finley → Max

The order of least to most acceleration will be the option C.
