I have a 20kg Weight fixed to the end of a wire. If I was to lift the weight 1 Meter thus having 1 Meter of slack in the wire and let go of the weight. What will the force be on the wire when the weight stops. I'm looking for a formulas etc so I can size up either a new rope or alter the design of the weight on the end of the rope so it's not as heavy. I've tried several equations and have now got totaly confused as to which way to go.

It depends on how rigidly the wire holds it.
If you could calculate a stopping distance that is well within the elastic limit of your wire, then you could calculate deceleration.
Once you know that use F=ma to calculate the force.

I agree with the F=ma part above^^^^ but would you also have to consider the potential and kinetic energy of the weight?
