Hey, I think this is a joke but not a cruel one. I'm not a student anymore but I can tell you that your formula is good. For rocket thrust I would use the following formula: F = m dot * Ve + (pe - p0) * Ae. This is an equation. What you stated was an expression. Also, temperture is not lost; it's a function of mass and velocity or E; you transformed it. Nasa has a great website and simulator; it can answer all your questions. Just thought I could poke some fun back at ya,

. Thanks for making me use my brain again!
