Question

1. stan was running a on a trail in a wooded area next to his house. he generally runs at a pace of 3 m/s. while stan was running he realized he was going to have to pass the person that was running in front of him. to do this, stan had to run at a pace of 7 m/s for about 2 seconds. what was stans acceleration during this time?

o 2 m/s²
o 2 m/s
o 5 m/s²
o 5 m/s
clear all

Explanation:

Step1: Identify initial and final velocities and time

Initial velocity $u = 3\ m/s$, final velocity $v=7\ m/s$, time $t = 2\ s$.

Step2: Use acceleration formula

The formula for acceleration $a=\frac{v - u}{t}$. Substitute the values: $a=\frac{7 - 3}{2}$.

Step3: Calculate acceleration

$a=\frac{4}{2}=2\ m/s^{2}$.

Answer:

$2\ m/s^{2}$
