Thank you for your help. I am totally ignorant in the subject of physics. I am very impressed with the help you have provided and although I am not a student of any kind of physics I will review my ideas on this matter.

Of course, it just takes longer. I appreciate what you are saying. I do believe I solved my problem. Unless somebody objects to I think I cracked it. I don't do physics, but its sure uselfull! In fact... necessary :)

I still think it is I who has formulated the question all wrong due to my ignorance. Once again thank you for your patience. One Watt is a measuremente equal to one joule per second. The TOTAL amount of electricity available to me is 2,943W for ONE second only. So that means I have potentially...

not if the fuel runs out, I am limited on that. So if my electricity runs out...

I can see my limitation that I only have 2,943 Watt of electricity in total. Sorry if I was not clear. Know nothing of physics and you are all helping me a great deal. I don't have an infinite electricity capability. 2,943 Watt is my limit. This is the equivalent of 2,943 joules that I have in...

Are we suggesting that a small amount of electricity power can lift a large weight? Time is not an issue so if it takes a second, a minute or an hour it does not matter.

Sorry for clarity sake Well, maybe I set out the problem wrong. I simply wanted to know if I can lift 100kg with 2,943Watts. I know the units are of different type but I would like to know if I could in theory or even in practice lift the weight in any way with the energy provided in Watts.

Hello, I am not a physics student, and I have a simple question/challenge. I want to lift 100kg from the floor by 5 meters. I have 2,943 Watts of power to do this. Is it possible? As i understand this is not possible. The force that 2,943 Watts provides is 588,6 Newtons using the...

Homework Statement This is my 1st post here, so I will do my best. The following question is part of a number of probability density functions that I have to prove. Once I have the hang of this I should be good for the rest, here is the question: Prove that the following functions are...
