Understanding the Concepts

* Newton's Second Law: This law states that the acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass. The equation is: F = ma (where F is force, m is mass, and a is acceleration)

* Net Force: The net force is the vector sum of all forces acting on an object. In this case, the only force we're considering is the horizontal tow line.

Calculation

1. Identify the known values:

* Mass (m) = 1000 kg

* Force (F) = 800 N

2. Use Newton's Second Law to solve for acceleration (a):

* F = ma

* a = F / m

* a = 800 N / 1000 kg

* a = 0.8 m/s²

Answer: The acceleration of the automobile is 0.8 m/s².
