The answer is b. According to the law of conservation of energy, energy can never be created nor destroyed, only transferred from one form to another.
To determine the acceleration of the car, we use equation of motion
Here, v is final velocity of the car, u is the initial velocity of the car, a is the acceleration of the car in time t.
Given, 
, u=0 because car accelerate from 0 and t = 3.40 s.
Substituting these values in above equation, we get
In mi/ h.s,
1 m = 0.000621371 mile.
1 s = (1/3600 ) hour = 0.000277778 hour.
Therefore,
