Question

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

Answer 1

The correct answer is option C.

Step-by-step explanation:

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

`Acceleration =(Velocity)/(Time)`

Acceleration of Xander =
`a_x`

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

`a_x=(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=(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=(7.3 m/s)/(1.2 s)=6.0833 m/s^2`

`a_x<a_f<a_m`

Xander → Finley → Max

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