@ThugLife13 no, its (m1 + m2 - M) c^2…because (m1+m2) is the final mass, so you have to subtract the first mass.

This test was much harder than December imho, and I expect the percentiles to drop…the questions seem easy at first, but they really weren’t…many tricks in the last couple of words in the sentence.

The first questions you’ve mentioned are correct (at least I think) except #4…where you need to use a meter and a stop watch.
