1. Understand the Concepts

* Force (F): A push or pull that can cause a change in motion. 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: 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 formula is: F = ma

2. Apply the Formula

We are given:

* Force (F) = 10 N

* Mass (m) = 20 kg

We need to find acceleration (a).

Rearranging the formula to solve for acceleration:

* a = F / m

3. Calculate

* a = 10 N / 20 kg

* a = 0.5 m/s²

Answer: The acceleration of the 20 kg mass is 0.5 m/s².
