Homework Help: Regelation: Wire and Ice Relationship?

  1. Sep 26, 2010 #1
    Hi, I'm not sure if this is in the right place, so sorry if it isn't.
    So basically, I need to figure out a hypothesis to find out the relationship between force (or pressure) and velocity when a wire moves through ice. I am having difficultly finding the right formula(s) to find the expected relationship.
    If I wasn't clear enough, I am planning to hang masses to both sides of a wire, have the wire pass through the ice, and for the ice to refreeze again. I will be calculating the velocity of the "wire" as it passes through the ice when I change the masses.

    2. Relevant equations
    What I thought of using were several formulas and combine them together. I also did some research and here is what I got:
    Work = Change in energy = Force * Distance
    Pressure = Force/Area
    Q=mL (Latent heat)
    Q= Work + U (internal energy change)

    3. The attempt at a solution
    Here is one of my attempts, I'm not sure if it's even valid:
    P = Force / Area = W/V (Energy(work) / Volume)
    P = (1/2mv^2) / Volume
    F/A = (1/2mv^2) / Volume
    Therefore, as the mass increases by "x", the velocity increases by "x^2".
    Is this a valid response? Would it work? Also, is there any way that I can input latent heat into the formulas?

    Thanks in advance!
