If a force of 2,000 Newtons is applied to a 1,000 kg car, what is the car's acceleration?

To determine the car's acceleration, we can use Newton's second law of motion, which states that the acceleration of an object is equal to the net force acting on it divided by its mass. This relationship is expressed mathematically as:

[ a = \frac{F}{m} ]

where ( a ) is the acceleration, ( F ) is the applied force, and ( m ) is the mass of the object.

In this scenario, the applied force ( F ) is 2,000 Newtons, and the mass ( m ) of the car is 1,000 kg. Plugging these values into the equation gives:

[ a = \frac{2000 , \text{N}}{1000 , \text{kg}} = 2 , \text{m/s}^2 ]

Thus, the car's acceleration is 2 m/s². This means that for each second that the force is applied, the velocity of the car increases by 2 meters per second. Therefore, this choice accurately reflects the calculation according to Newton's second law.
