Homework Help: Physics

Posted by Julia on Sunday, March 2, 2008 at 6:09pm.

A man lifts a 21.1 kg bucket from a well and does 3.1 kJ of work. How deep is the well? Assume that the man lifts the bucket at constant speed. Answer in units of m.

I am not sure if I did this right:

(mg)(d)= Wnet

(21.1 kg)(9.81)(d)= 3100J
d= 14.98 meters
