1. OK, Two blocks are hanging from a ceiling, with a rope between them. The top block is 72 N, while the bottom block is 150 N. What is the tension in the rope between them? 2. Relevant equations 3. The attempt at a solution My confusion is that I'm not sure if we're supposed to include the top block in this situation. Thus far, I know how to calculate the bottom tension in a rope (only include the bottom block), and the top tension in a rope (include both), but just simply saying tension gets me a little confused. If this sounds dumb, then please excuse me, I decided to read ahead of the class, so I'm on my own here.
