Cevap
To find the acceleration of the car, we can use the equation of motion:
where:-
is the distance covered,-
is the initial velocity,-
is the time taken,-
is the acceleration.Given:-
meters,-
meters/second (since the car is initially at rest),-
seconds.Substituting the values into the equation:
Therefore, the approximate acceleration of the car is:B.
