Final answer:
The correct relationship among force, mass, and acceleration is defined by Newton's second law of motion as Force equals mass times acceleration (F = ma). For a wagon with a mass of 55 kg and acceleration of 0.0255 m/s², the force equates to 1.4025 newtons.
Step-by-step explanation:
The relationship among force, mass, and acceleration is described by Newton's second law of motion. The correct relationship is given by the equation F = ma, where F stands for force, m for mass, and a for acceleration. Thus, the correct answer is (b) Force equals mass times acceleration.
To apply this law, consider a wagon with a mass of 55 kg that is undergoing an acceleration of 0.0255 m/s². Using the equation, the force exerted on the wagon can be calculated as F = ma = 55 kg × 0.0255 m/s², which equals 1.4025 newtons (N).
