Answer
Average accleration is 1.1 m/s² .
Option (D) is correct .
Explanation:
Formula
[tex]Average\ accleration = \frac{v_{final}-v_{initial}}{t_{final}-t_{initial}}[/tex]
As given
An Olympic sprinter can go from a state of rest to 11 meters per second in 10 seconds.
[tex]v_{initial} = 0\ meter\ per\ second[/tex]
[tex]v_{final} = 11\ meter\ per\ second[/tex]
[tex]t_{initial} = 0\ second[/tex]
[tex]t_{final} = 10\ second[/tex]
Putting all the values in the formula
[tex]Average\ accleration = \frac{11-0}{10-0}[/tex]
[tex]Average\ accleration = \frac{11}{10}[/tex]
Average accleration = 1.1 meter per second²
Therefore Average accleration is 1.1 m/s² .
Option (D) is correct .
