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 = ma

* F = force (in Newtons)

* m = mass (in kilograms)

* a = acceleration (in meters per second squared)

Solving the Problem

1. Identify the knowns:

* Mass (m) = 22 kg

* Force (F) = 12 N

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

* a = F / m

3. Plug in the values:

* a = 12 N / 22 kg

4. Calculate the acceleration:

* a ≈ 0.55 m/s²

Answer: The acceleration of the cart is approximately 0.55 m/s².
