Divide the problem into two or more smaller problems that each involves one central physics idea. Write a brief outline of your mathematical procedure. Include a labeled sketch of your setup. Identify which physics ideas you will use for each part. Describe how you will model the objects, interactions and processes you will use in your mathematical model.
