Question

Xander reached a final velocity of 4.5 m/s for 3.5 seconds. Finley reached a final velocity of 3.6 m/s for 4.2 seconds. Max reached a final velocity of 7.3 m/s for 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

Answer 1

Arranging the acceleration of Xander, Finley and Max from least to most, we have: Finley, Xander, Max

The correct answer to the question is the last option. Finley, Xander, Max

To know which option is correct, we shall determine the acceleration of each person. This can be obtained as follow:

For Xander:

Initial velocity (u) = 0 m/s

Final velocity (v) = 4.5 m/s

Time (t) = 3.5 s

Acceleration (a) =?

$a = \frac{v - u}{t} \\\\a = \frac{4.5 - 0}{3.5} \\\\a = \frac{4.5}{3.5}$

a = 1.29 m/s²

For Finley:

Initial velocity (u) = 0 m/s

Final velocity (v) = 3.6 m/s

Time (t) = 4.2 s

Acceleration (a) =?

$a = \frac{v - u}{t} \\\\a = \frac{3.6 - 0}{4.2} \\\\a = \frac{3.6}{4.2}$

a = 0.86 m/s²

For Max:

Initial velocity (u) = 0 m/s

Final velocity (v) = 7.3 m/s

Time (t) = 1.2 s

Acceleration (a) =?

$a = \frac{v - u}{t} \\\\a = \frac{7.3 - 0}{1.2} \\\\a = \frac{7.3}{1.2}$

a = 6.08 m/s²

SUMMARY:

Xander's acceleration = 1.29 m/s²

Finley's acceleration = 0.86 m/s²

Max's acceleration = 6.08 m/s²
