Question 3 Find the optimal mass for a three-stage launch vehicle that is required to lift a 4,000 kg payload to a speed of 10.0 km/s. The parameters of each stage are given below: Stage Specific Impulse (s) Structural ratio 1 320 0.12 2 350 0.15 3 390 0.18 (a) Write-down the Lagrange function for the mass optimization problem and derive the equation for the Lagrange multiplier, n. [3 Marks] (b) Find the value of the Lagrange multiplier, n with the accuracy of two decimal places (show all workings) by the Bisection method. Use the interval n = [0.4 0.5] to initialise your solution. [4 Marks]
