Understanding the Concepts

* Force (F): The push or pull on an object. Measured in Newtons (N).

* Mass (m): The amount of matter in an object. Measured in kilograms (kg).

* Acceleration (a): The rate of change of velocity. Measured in meters per second squared (m/s²).

Newton's Second Law of Motion

Newton's Second Law of Motion states the relationship between force, mass, and acceleration:

* F = m * a

Solving the Problem

1. Identify the knowns:

* Force (F) = 200 N

* Acceleration (a) = 5 m/s²

2. Rearrange the formula to solve for mass (m):

* m = F / a

3. Substitute the values:

* m = 200 N / 5 m/s²

4. Calculate the mass:

* m = 40 kg

Therefore, the mass of the cement block is 40 kg.
