a) Single Stage: Consider a single stage rocket. The payload is mL = 100kg. The structural mass of each stage is 1/7 times the propellant mass for that stage (e.g. ms1 = mp1/7). The fuel has an Isp = 300s. What is the total weight of the rocket required to achieve a v = 6km/s? (b) Two Stage: Suppose you have a 2 stage rocket with payload mass of mL = 100kg. The structural mass of each stage is 1/7 times the propellant mass for that stage (e.g. ms1 = mp1/7). The total mass of the second stage (including payload) is 3 times the mass of the payload. What is the total weight of the rocket required to achieve a v = 6km/s
