Question

If a car with a mass of 1,200 kg traveling westward at 30 m/s is
slowed to a stop in 3 s, then what was the net force acting on
the car?

Answer 1

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:

$F = \frac{m(v\;-\;u)}{t}$

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;

$F = \frac{1200 \times (0\;-\;30)}{3}\\\\F = \frac{1200 \times (-30)}{3}\\\\F = \frac{-36000 }{3}$

Net force = -12000 Newton.
