Answer:
[tex]-1.59 \times 10^{-3} m/s^2[/tex] is the acceleration of the person.
Explanation:
Given that,
Initial velocity of the person is 4 m/s
The race is completed in 41.67 minutes = [tex]41.61 \times 60[/tex] = 2500.2 seconds.
The final velocity is 0 m/s as the person completes the race and the speed will be 0 at end of the race.
using the formula,
V = U + at
where,
"V" is "Final velocity"
"U" is "Initial velocity"
"a" is "acceleration"
"t" is "time"
Now, find the "acceleration" by substituting the values in the above formula,
[tex]0=4+a\times 2500.2[/tex]
[tex]\frac{-4}{2500.2}=a[/tex]
[tex]-1.59 \times 10^{-3} m/s^2[/tex] is the "acceleration" of the person.
