Problem: Minimize the total mass M = M1+ M2 + M3 of the rocket subject to the constraint that the required velocity vs is attained. Apply the method of Lagrange multipliers. Find the minimum of M as a function of vs. (1) A final velocity of 17500 mi/h is required to place a rocket into orbit 100 miles above the earth's surface. Suppose that the structural factor S = 0.2 and the exhaust speed is c= 6000 mi/h. Find the minimum total mass M of the rocket as a function of A. Find the mass of each individual stage as a function of A. (2) A final velocity of 24700 mi/h is required to escape earth's gravity. Suppose that the structural factor S = 0.2 and the exhaust speed is c = 6000 mi/h. Find the mass of each individual stage that would minimize the total mass and allow the rocket to propel a 500 pound probe into deep space.
