1. The problem statement, all variables and given/known data During a .0050 second time period a rocket expels 1.000kg of gas at a velocity of 5000 m/s. Calculate the rockets average Thrust, as well as Impulse. http://imgur.com/a/uE9dV I am going to use this note for reference on a test and want to rock solid about it. 2. Relevant equations I have the formulas given by my professor are Thrust= v exhaust * (delta mass / time) Impulse rocket= v exhasut (delta mass)= delta p rocket 3. The attempt at a solution Like I said I want to be sure of this so I can refer to it later. Here is my best try Thrust= (5000m/s)*(1.000kg/.0050s) = 5000 m/s * 200 kg/s= 10000000 kg m/s Impulse= 5000 m/s (1.000 kg) = 5000kg m/s So please tell me if and where I have gone wrong.
