Understanding the Concepts

* Force (F): The push or pull that causes an object to accelerate. 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: Force = Mass x Acceleration (F = m * a)

Solving the Problem

1. We know:

* Force (F) = 200 N

* Acceleration (a) = 5 m/s²

2. We need to find:

* Mass (m)

3. Rearrange the formula to solve for mass:

* m = F / a

4. Substitute the values:

* m = 200 N / 5 m/s²

5. Calculate:

* m = 40 kg

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