Laboratory Homework Number 2 Solution MATLAB script for solution procedure for both Questions 1 and 2 can be found on the course website under the Laboratory Homework Page.
Question 1: (10 points)
T1 = 20. T2 = 23. T3 = 27. T4 = 66. T5 = 67.
Question 2: (20 points)
The plot should look like:
Grading of Question 2: 8 points: Does the plot look generally correct (i.e. does the calculation seem to be done properly)? 2 points: Is the z-axis in km/s and labeled properly? 2 points: Is the x-axis labeled as a Mass Ratio?

2 points: Is the y-axis specific impulse labeled with units of seconds? 2 points: Does the plot have an appropriate title? 2 points: Is there a color bar? 2 points: Is the chart located in a MS Word document with some comments on the results.
Some sample comments may include:
The rocket with the highest burn-out velocity is the one with the highest specific impulse and the highest mass ratio. The rocket has a fixed payload and structural weight totaling 1000 kg, and hence the final velocity of the rocket is a maximum when the rocket has the most fuel. The performance of this rocket continually increases with specific impulse and with mass ratio (or more precisely with fuel mass). The mass ratio impacts the burn-out velocity logarithmically and the specific impulse impacts the burn-out velocity linearly.
