Understanding the Concepts
* Newton's Second Law: 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
* F = Net force (in Newtons)
* m = Mass (in kilograms)
* a = Acceleration (in meters per second squared)
Solving the Problem
1. Identify the knowns:
* Force (F) = 7.0 N
* Mass (m) = 3.2 kg
2. Rearrange the equation to solve for acceleration (a):
* a = F / m
3. Substitute the known values and calculate:
* a = 7.0 N / 3.2 kg
* a ≈ 2.19 m/s²
Answer: The acceleration of the model airplane is approximately 2.19 meters per second squared.
