Question

An Olympic sprinter can go from a state of rest to 11 meters per second in 10 seconds. What is the average acceleration of the sprinter?

A.
0.9 m/s

B.
110 m/s

C.
110 m/s²

D.
1.1 m/s²

Answer 1

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 2

Average accleration is 1.1 m/s² .

Option (D) is correct .

Step-by-step explanation:

Formula

`Average\ accleration = (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 = (11-0)/(10-0)`

`Average\ accleration = (11)/(10)`

Average accleration = 1.1 meter per second²

Therefore Average accleration is 1.1 m/s² .

Option (D) is correct .
