Read each scenario and then answer the question. Scenario A: A 7 N bucket is raised a distance of 6 m. Scenario B: A 10 N bucket is raised a distance of 4 m. Scenario C: A 12 N bucket is raised a distance of 3 m. Which scenario requires the most work?

The work done is equal to the weight (mg) of the bucket times the altitude at which it is raised, h:

W=mgh
Let's calculate the work for the 3 scenarios:

W_A = (7 N)(6 m)=42 J

W_B=(10 N)(4 m)=40 J

W_C=(12 N)(3 m)=36 J

So, the scenario which requires more work is scenario A.
