<u>Answer</u>
The acceleration is
to the nearest tenth
<u>Explanation</u>
Since the car was travelling at
before it starts to decelerate, the initial velocity is
.
The final velocity is
, because the car came to a stop.
The time taken is
.
Using the Newton's equation of linear motion,
, we find the acceleration by substituting the known values.
This implies that,

This gives us,


We divide both sides by 15 to get,

or

The best answer is D. field lines should always be crossing each other.
