-10,000 = 2000 x specific heat Cu x (Tfinal-95)

Sole for Tfinal.

I skipped through it but didn't get that number. My best guess is that you looked up the specific heat of copper and found 0.385 but that number is joules/g. You must convert that to calories OR you must convert the 10,000 calories to joules.

Convert 0.385 J/g to calories by dividing by 4.184. Something like 40 C or so should be the answer.
