Answer:
The acceleration of the car will be 
Explanation:
We have given that distance from stop sign s = 200 m
Time t = 0.2 sec
We have to find the constant acceleration
Now from second equation of motion 
So the acceleration of the car will be
The answer, using an indicator to measure the hydrogen ion concentration of a solution, is correct
