Understanding the Concepts

* 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. Mathematically, it's expressed as:

* F = m * a

* where:

* F = Force (in Newtons)

* m = Mass (in kilograms)

* a = Acceleration (in meters per second squared)

Calculation

1. Identify the given values:

* Mass (m) = 25 kg

* Force (F) = 10 N

2. Rearrange the formula to solve for acceleration (a):

* a = F / m

3. Substitute the values and calculate:

* a = 10 N / 25 kg

* a = 0.4 m/s²

Answer: The acceleration of the 25 kg mass is 0.4 m/s².
