Final answer:
The acceleration of a particle with mass 'm' experiencing a net force 'F' is calculated as a = F/m, which is derived from Newton's second law of motion. For example, a wagon with a mass of 55 kg accelerating at 0.0255 m/s² has a force of 1.4025 N acting on it.
Step-by-step explanation:
The acceleration of a particle with mass 'm' experiencing a net force 'F' is found using Newton's second law of motion, which states that the net force on an object is equal to the mass of the object multiplied by its acceleration (a). Therefore, the correct formula to find acceleration is a = F/m, meaning the acceleration is the net force divided by the mass of the object.
As an example, if a wagon with mass 55 kg accelerates at a rate of 0.0255 m/s², the net force on the wagon can be calculated as:
F = ma
F = 55 kg × 0.0255 m/s²
F = 1.4025 N
This tells us the force in newtons that is acting on the wagon.
