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?

Xander reached a final velocity of 4.5 m/s for 3.5 seconds. Using the equation vf = vi + at, where vf is the final velocity, vi is the initial velocity, a is the acceleration, and t is the time, we can solve for the acceleration:
4.5 = 0 + a(3.5)
a = 4.5/3.5
a ≈ 1.29 m/s²
Finley reached a final velocity of 3.6 m/s for 4.2 seconds, so:
3.6 = 0 + a(4.2)
a = 3.6/4.2
a ≈ 0.86 m/s²
Max reached a final velocity of 7.3 m/s for 1.2 seconds, so:
7.3 = 0 + a(1.2)
a = 7.3/1.2
a ≈ 6.08 m/s²
Therefore, the correct order from least to most acceleration is:
