Final answer:
Force on an object is calculated using Newton's second law of motion, F = ma. A wagon with mass 55 kg and acceleration 0.0255 m/s² experiences a force of 1.4025 N.
Step-by-step explanation:
The subject of the question is Physics, specifically related to Newton's second law of motion. According to this law, the force F on an object is equal to its mass m multiplied by its acceleration a. This can be represented by the formula F = ma.
For the example provided, a wagon with a mass of 55 kg accelerating at a rate of 0.0255 m/s², you would calculate the force on the wagon by plugging the values into the equation:
F = m × a
F = 55 kg × 0.0255 m/s²
F = 1.4025 N
Therefore, the force exerted on the wagon is 1.4025 Newtons (N).
