Understanding the Concepts

* Newton's Second Law of Motion: This law states that the force acting on an object is directly proportional to its mass and acceleration. Mathematically, it's expressed as:

* Force (F) = Mass (m) * Acceleration (a)

Calculation

1. Given:

* Mass (m) = 1600 kg

* Acceleration (a) = 4.5 m/s²

2. Apply Newton's Second Law:

* Force (F) = 1600 kg * 4.5 m/s²

* Force (F) = 7200 N (Newtons)

Answer: The force required to give the automobile an acceleration of 4.5 meters per second squared is 7200 Newtons.
