How much work is required to lower a 120-pound weight from a height of 3 feet?

To determine the amount of work required to lower a weight, we can apply the formula for work done against gravity, which is given by the product of weight and the height from which it is lowered.

In this scenario, the weight being lowered is 120 pounds and it is being lowered from a height of 3 feet. The work done can be calculated by multiplying the weight by the height:

Work = Weight × Height

Substituting the values we have:

Work = 120 pounds × 3 feet = 360 foot-pounds.

This calculation shows that the total work required to lower the weight 3 feet is 360 foot-pounds. This aligns with the chosen answer, indicating that the calculation and application of the work-energy principle in this context is sound and correctly reflects the physics involved.

Other choices do not match this calculation, as they either misrepresent the multiplication of the weight and height or involve different contexts unrelated to the scenario presented. Thus, the answer of 360 foot-pounds accurately represents the work done in lowering the weight.
