ehild, thank you for your reply and I apologize for this far too late of response. I figured out the answer to this problem after grinding the problem for a while. I am done with my final for the first part of physics! I can not wait for the second part in a week :) Thanks again and talk to you...

Thanks again for your inspiring words child, they most definitely resonate in my mind. I hope to get to the level of knowledge in physics that allows me to help other folks on here, your work is truly inspiring. I appreciate your time and knowledge with my regard to the PF team, you guys are the...
Thanks for the guidance. I will definitely always keep that in the back of my mind when I am solving problems. Physics takes a great amount of practice, but it is worth it because it is real knowledge! Thanks again... I am still impressed! :)
c=v^2/(2ΔT)
I believe this is the answer. If it is, thanks for the indescribable genius -answering my question with knowledge loaded question! I hope I am not getting ahead of myself.
I am not sure if I did anything before evaluating the kinetic energy. I am assuming the mass is not a limiting factor, and that energy change is actually indicated by the temperature change of 10 kelvin? Now, I just tried that mass and a couple of others and I still got the same answer. Does...
