Question

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 at the same location from rest. Which lists them from least to most acceleration?

Answer 1

Answer: Finley, Xander, Max

Explanation:

The acceleration of each runner is given by:

$a=\frac{v-u}{t}$

where

v is the final velocity

u is the initial velocity

t is the time taken

- Xander: his acceleration is $a=\frac{4.5 m/s-0}{3.5 s}=1.29 m/s^2$

- Finley: his acceleration is $a=\frac{3.6 m/s-0}{4.2 s}=0.86 m/s^2$

- Max: his acceleration is $a=\frac{7.3 m/s-0}{1.2 s}=6.08 m/s^2$

So, in order from least to most acceleration:

Finley, Xander, Max

Answer 2

the answer is Finley, Xander, Max
