hmmm say if it was made out of copper n iron copper having 400 specific heat heat capacity Iron having 890 specific heat and the mixture had 780 specific heat capacity ^ assume the values are that can u show me how to do the inverse problem to find the composition?

IS it possible? say if the specific heat is 800 and the composition is made up of 2 materials one which has specific heat of 850 and the other of 750

oh i see... i got... 674 m/sec doesn't seem right Ek = 334800 x .68?

um I am still puzzled LOL can u show me the steps?
