A sprinter increases the speed from 0 meters per second to 9 meters per second in 2 seconds. what is the acceleration

The acceleration is

Step-by-step explanation:

Use the equation of motion,

where u=0m/s is the initial speed, v=9m/s is the final speed and t=2 seconds is the time.

We substitute the values into the equation and solve for the acceleration, a

This means that;

Divide both sides by 2 to get:

answer: 140

step-by-step explanation:

so just add all then it will be your answer but i am not pretty sur eif it is but hope this i am here to people
