Question

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?

Answer 1

Answer: Scenario A

Explanation: i got it correct on edge

Answer 2

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.
