Verified Answer :

an Olympic sprinter can go from a state of rest to 11 meters per second in 10 seconds. 1.1 m/s² is the average acceleration of the sprinter

Answer

Average accleration is 1.1 m/s² .

Option (D) is correct .

Explanation:

Formula

\(Average\ accleration = \frac{v_{final}-v_{initial}}{t_{final}-t_{initial}}\)

As given

An Olympic sprinter can go from a state of rest to 11 meters per second in 10 seconds.

\(v_{initial} = 0\ meter\ per\ second\)

\(v_{final} = 11\ meter\ per\ second\)

\(t_{initial} = 0\ second\)

\(t_{final} = 10\ second\)

Putting all the values in the formula

\(Average\ accleration = \frac{11-0}{10-0}\)

\(Average\ accleration = \frac{11}{10}\)

Average accleration = 1.1 meter per second²

Therefore Average accleration is 1.1 m/s² .

Option (D) is correct .
