Which statement about the amount of work completed by Individual M and Individual N is true?

• A. Both individuals will have done the same amount of work because the force was applied for the same duration of time.
• B. Individual M will have done less work because the object was moved a greater distance.
• C. Individual N will have done less work because the object was moved a shorter distance.
• D. Individual M will have done more work because the muscle contracted faster to achieve synchrony with Individual N.

Answer: (C)

The correct statement is that Individual N will have done less work because the object was moved a shorter distance. In physics, the work done is defined as the product of the force applied to an object and the distance over which that force is applied, expressed mathematically as Work = Force × Distance × cos(θ), where θ is the angle between the force and the direction of motion. When comparing the work done by Individual M and Individual N, the critical factor is the distance over which the force was applied, assuming the force exerted was comparable. If Individual N moved the object a shorter distance than Individual M, then the work done by Individual N will necessarily be less, regardless of other factors such as the duration over which force was applied or the speed at which the muscle contracted. Thus, even if both completed their tasks in the same amount of time or with similar levels of effort, the work calculation fundamentally depends on the distance moved. In this case, since Individual N moved the object a shorter distance, it directly correlates to less work done compared to Individual M.
