A winch with a power rating of 400 W lifts a 200kg object off the ground at a constant velocity for 17 seconds. How high was the object lifted? What is the object total energy?
Please indicate which equation you use, what variable corresponds to each number, and how you got the number that goes with the variable.
Thanks!

I have a better idea. You do all that and I will happily critique your work and thinking.

If you could just post the equations that would be helpful in this problem that would be great. I am sure I can figure it out form there. Also does TE stand for total energy?
