The rocket is redesigned and a two stage booster is used. The payload weight is the same (40 kN). The weight of fuel is 420 kN fuel and is stored in stage 1 booster (300 kN fuel and 30 kN structural booster mass) and stage 2 booster (120 kN fuel and 10 kN structural booster mass), respectively. The fuel burn rate and the exhaust speed are still the same. Assume that the average value of the gravitational acceleration is 9.6 m/s2 and the rocket start from rest. (d) Determine the speed at the first burnout. (e) Determine the speed at the second burnout. (f) Compare the performance of single stage rocket and two stages rocket using the above calculation results.
