Understanding the Concepts

* Newton's Second Law of Motion: This law states that the force (F) acting on an object is equal to its mass (m) multiplied by its acceleration (a). The formula is: F = m * a

Applying the Formula

1. Identify the known values:

* Mass (m) = 18 kilograms

* Acceleration (a) = 36 m/s² (assuming you're using standard units)

2. Plug the values into the formula:

* F = 18 kg * 36 m/s²

3. Calculate the force:

* F = 648 Newtons (N)

Answer: A force of 648 Newtons is required to accelerate a body with a mass of 18 kilograms at a rate of 36 m/s².
