I would like to ask some people to please check my math for me with regard to SF2 missile acceleration. First, I recommend opening the links below as tabs in a separate browser window, plus your Windows calculator in scientific mode with the unit conversion panel open. Calculating rocket acceleration<-----Formula Source. Convert Meters Per Second Squared to Standard Gravity Convert Standard Gravity to Meters Per Second Squared Convert Pounds-force to Newtons Velocity, Acceleration and Time Calculator Uniform motion (travel distance) Calculator WesternElectricNikeHerculesBrown.pdf<-----The bulk of the missile data was drawn from this document. Missile Data <-----This was used to fill in some blanks. Now, here is the issue. I am calculating the booster and sustainer acceleration g-force for two missiles. ||-----Formulas-----|| Weight (in kg) = Mass (in kg) x 9.81 Resultant Force (newtons, N) = Thrust (in N) – Weight (in kg) Acceleration (m/s2) = Resultant Force (newtons, N) ÷ Mass (kilograms, kg) //-----MIM-3 Data-----\\ The MIM-3 missile has a combined missile-booster weight of 2499.3 lbs (1133.663410341 kg). The missile’s weight is 1193.3 lbs (541.271775121 kg). The booster’s weight is 1306 lbs (592.39163522 kg). The booster produces 59,000 lbs of thrust (262445.0753 N) for 3.5 seconds. The sustainer produces 2600 lbs of thrust (11565.3762 N) for 20.8 seconds. //-----MIM-3 Calculations-----\\ Missile With Booster 11121.23805544521 kg = 1133.663410341 kg x 9.81 251323.83724455479 N = 262445.0753 N– 11121.23805544521 kg 221.69176049261208816117588018214 m/s2 = 251323.83724455479 N ÷ 1133.663410341 kg 22.606268 g = 221.69176049261208816117588018214 m/s2 Missile With Sustainer 5309.87611393701 kg = 541.271775121 kg x 9.81 6255.50008606299 N = 11565.3762 N – 5309.87611393701 kg 11.557040979394478940811698611408 m/s2 = 6255.50008606299 N ÷ 541.271775121 kg 1.178490g = 11.557040979394478940811698611408 m/s2 For Data File...
