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 represented as:

* F = m * a

* F = Force (in Newtons, N)

* m = Mass (in kilograms, kg)

* a = Acceleration (in meters per second squared, m/s²)

Calculation

1. Rearrange the formula to solve for acceleration:

* a = F / m

2. Plug in the values:

* a = 68.6 N / 10 kg

3. Calculate the acceleration:

* a = 6.86 m/s²

Answer: The acceleration of the 10 kg mass is 6.86 m/s².
