Rank the net forces acting on boxes of various masses from greatest to least: c, b, a, d. Which box has the greatest net force?

To determine which box has the greatest net force, we need to consider Newton's second law of motion, which states that the net force acting on an object is equal to its mass multiplied by its acceleration (F = ma). The net force depends on both the mass of the object and the acceleration it experiences.

If we assume all boxes are subject to the same acceleration, the net force acting on each box directly relates to its mass. Therefore, the heavier the box (greater mass), the greater the net force, assuming the same acceleration for all.

When ranking the boxes from greatest to least net force, box c must have the greatest mass or higher acceleration compared to boxes b, a, and d under similar conditions. Since box c is identified as the one with the greatest net force, it indicates that it either has the largest mass or the highest acceleration.

In conclusion, box c has the greatest net force because it either has the highest mass or is subjected to greater acceleration compared to the other boxes. Understanding the relationship between mass, acceleration, and net force is crucial in solving these types of problems in physics.
