1. The problem statement, all variables and given/known data Small model rocketry engines are sized by specific impulse. One common size is a C6 engine. With each letter increase in engine size. The "C" engine is 10.0 N -s specific impulse. The "6" indicates that the engine produces an average thrust of 6 newtons. How much time does the engine burn? 2. Relevant equations P=mv J=F*T F*T=M(Vf-Vo) 3. The attempt at a solution Just started this unit today worked through the rest 10 problems only one that i have no clue about.
