Unformatted text preview: V ( t ), h ( t ) for the zero-drag case C D = 0. 2. Set C D = 0 in your program. Perform three separate calculations for t = 0 . 1s , . 05s , . 02s. Plot all three h i curves on one plot, and also include the exact h ( t ) solution. a) Does your algorithm appear to be consistent ? (see Lab 2 Notes). Explain. b) You will be using the spreadsheet to make rocket design decisions in subsequent labs (determine optimum water mass, importance of drag, etc). Based on the results in a), what do you recommend as a suitable t to use? State your criterion. Use your chosen t for the next part. 3. Perform three trajectory calculations for C D = 0 . 1 , . 2 , . 5. Plot the resulting h i . Com-ment on the importance of drag reduction for water rocket altitude performance....
