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

Answer:

Finley, Xander and Max

Explanation:

v = Final velocity

t = Time

u = Initial velocity = 0

a = Acceleration

From kinematic equations we get

$v=u+at\\\Rightarrow a=\dfrac{v-u}{t}=\dfrac{v-0}{t}\\\Rightarrow a=\dfrac{v}{t}$

Xander

v = 4.5 m/s, t = 3.5 s

$a=\dfrac{4.5}{3.5}\\\Rightarrow a=1.29\ \text{m/s}^2$

Finley

v = 3.6 m/s, t = 4.2 s

$a=\dfrac{3.6}{4.2}\\\Rightarrow a=0.86\ \text{m/s}^2$

Max

v = 7.3 m/s, t = 1.2 s

$a=\dfrac{7.3}{1.2}\\\Rightarrow a=6.083\ \text{m/s}^2$

The required list is Finley, Xander and Max.
