The net force acting on the car is equal to -12000 Newton.
<u>Given the following data:</u>
- Initial velocity = 30 m/s.
- Final velocity = 0 m/s (since the car came to a stop).
To determine the net force acting on the car:
<h3>How to calculate the net force.</h3>
Mathematically, the net force acting on the car is given by Newton's Second Law of Motion:

<u>Where:</u>
- u is the initial velocity.
Substituting the given parameters into the formula, we have;

Net force = -12000 Newton.
