Understanding the Concepts

* Force: A push or pull that can change an object's motion.

* Mass: The amount of matter in an object.

* Acceleration: The rate of change of velocity.

Newton's Second Law of Motion

Newton's Second Law of Motion states:

* Force (F) = Mass (m) x Acceleration (a)

Calculation

1. Identify the given values:

* Mass (m) = 10 kg

* Acceleration (a) = 2.0 m/s² (Assuming the acceleration is in meters per second squared)

2. Plug the values into the formula:

* Force (F) = 10 kg * 2.0 m/s²

3. Calculate the force:

* Force (F) = 20 N (Newtons)

Answer

The force needed to accelerate the wagon at a rate of 2.0 m/s² is 20 Newtons.
