## Projects

The student will be given a short, one or two sentences, description of a problem that uses no calculus terminology.

• Stage 1: The student's first task is to ask the right questions in order to recast the problem in the language of the appropriate mathematics. It also includes critique of the old submission.
• Stage 2: Then he is to explore the problem numerically and graphically with a spreadsheet and make an approximation of what the answer might be and ask further questions.
• Stage 3: Finally, the problem is solved analytically with the calculus tools and the answer is confirmed.

All the steps, the explanations of the methods, the data, the illustrations, and the computations are presented in writing. The methods should be based entirely on the material of the course.

The actual project statements are written as if by a person with no knowledge of calculus. That is why the problems may be poorly formulated, incomplete, and have many possible answers or none at all. As a result, the structure of the project might be much more complex than the three stages above.

Project statements:

• 1. How do I throw a ball down a staircase so that it bounces off each step? -- (fall 2016)
• 2. How should you throw a ball from the top of a $100$ story building so that it hits the ground at $100$ feet per second? -- (spring 2017, fall 2016)
• 3. I would like to use a cannon with a muzzle velocity of $100$ feet per second to bombard the inside of a fortification $300$ feet away with walls $20$ feet high. -- (spring 2017, fall 2016)
• 4. I have a toy cannon and I want to shoot it from a table and hit a spot on the floor $10$ feet away from the table. -- (spring 2017, fall 2016)
• 5. How hard do I have to push a toy truck from the floor up a $30$ degree incline to make it reach the top of the table at zero speed? -- (spring 2017, fall 2016)
• 6. How much does moving in or out of the passing lane affect the reading of a radar gun? -- (spring 2017, fall 2016)
• 7. How fast does the shadow of a falling ball on a sliding ladder move? -- (spring 2017)
• 8. How fast do I have to move my hand while spinning a sling in order to throw the rock $100$ feet away? -- (spring 2017, fall 2016)
• 9. Where should I stand in order to be best illuminated by two light bulbs on the ceiling if the amount of light is inversely proportional to the square of the distance? -- (spring 2017)

Instructions:

• A group should contain one or two persons.
• Your submission should be both on paper and in a digital format such as PDF (it will be linked here).
• It is a good idea to go digital from the beginning; for example, write with Latex or MS Word, draw with MS Paint, analyze data with MS Excel or Google spreadsheets.
• Include: the name, the title, introduction, conclusions, labeled pictures and tables, references, etc.
• The Excel file with the “free fall” equations is here for download, some explanations are here.
• Due date: April 23
