http://bildr.no/view/aWc4dW95 Above is a question that I posted on a school help site. This is the answer I got: https://www.scribd.com/document/352...usage-of-E-mc-2-for-v-much-smaller-then-c-ans Can you use this answer to show that the type of calculation that I tried in the attachement above where I got 26.5 and 27 would hold? Or if not. Why is the document an answer to my question. Can you put some of the formulas from the answer in use practically to the problem I posed where I ended up with 26.5 and 27?
