Understanding the Concepts

* Newton's Second Law of Motion: This law states that the force (F) acting on an object is equal to its mass (m) multiplied by its acceleration (a). Mathematically, this is represented as: F = m * a

Applying the Information

* Mass (m): 45 kg

* Acceleration (a): 2 m/s² (we'll assume you meant 2 meters per second squared)

Calculation

F = m * a

F = 45 kg * 2 m/s²

F = 90 Newtons (N)

Answer: You would need a force of 90 Newtons to accelerate your body at a rate of 2 m/s².
