Final answer:
The net force applied to a wagon with a mass of 12 kg and an acceleration of 0.5 m/s² is calculated using Newton's second law of motion, resulting in a force of 6 newtons.
Step-by-step explanation:
To determine the net force applied to a wagon with a mass of 12 kg that accelerates at a rate of 0.5 m/s², you can use Newton's second law of motion. This law is articulated as Force (F) equals mass (m) times acceleration (a), or F = m × a in formula form. Substituting the given values into this formula gives:
F = 12 kg × 0.5 m/s² = 6 N.
Therefore, the net force applied to the wagon is 6 newtons.
