Man Lifts 15kg Bucket from Well: Calculating Depth

[parwana]

If a man lifts a 15.0 kg bucket from a well and does 3.00 kJ of work, how deep is the well? Assume that the speed of the bucket remains constant as it is lifted.

What is the definition of work? Look it up, and I'm sure you'll be able to solve this without any difficulties.

Further on, think about why constant velocity is mentioned. What are the forces that are acting on the bucket? In what relation are they (because of constant velocity)?

 

[parwana]

Work= Force times change in x
I got it

I used F= ma to find F

then plugged it in the equation to find x

 

[gunblaze]

F= ma to find F

Its supposed to be mg where g is ur acceleration of free fall.
