2. Analysis the 45 launching degree videos, 

3. Analysis the the maximum height videos

4. Helping with second part of the code, changing all then code into vectors, set up the code for air drag, set up the code for initial velocity in term of stretching length, setup input of spring constant, mass, stretch length, angle of launching and print them out.

5. Explain the graph means in the google slides

6. Point out the trouble that we facing during the project.

7. Paste a copy of the code for further use.
