Answer :
The net force acting on the car is equal to -12000 Newton.
Given the following data:
- Mass = 1,200 kg
- Initial velocity = 30 m/s.
- Final velocity = 0 m/s (since the car came to a stop).
- Time = 3 seconds.
To determine the net force acting on the car:
How to calculate the net force.
Mathematically, the net force acting on the car is given by Newton's Second Law of Motion:
[tex]F = \frac{m(v\;-\;u)}{t}[/tex]
Where:
- m is the mass.
- t is the time.
- u is the initial velocity.
- u is the final velocity.
Substituting the given parameters into the formula, we have;
[tex]F = \frac{1200 \times (0\;-\;30)}{3}\\\\F = \frac{1200 \times (-30)}{3}\\\\F = \frac{-36000 }{3}[/tex]
Net force = -12000 Newton.
