MEMORANDUM
Date: October 15, 1999
To: Research and Development Team
From: Wes Graham
You probably remember that I mentioned this contract at the last
departmental meeting. Attached are copies of the letter and basic design
specs, along with a list of relevant materials in stock. Start working up a
plan so you can go into the lab as soon as possible. Work in SI, and keep
track of significant figures. Present your plan to me before you start work.
Make sure your plan includes the equipment you’ll need and the measurements
you are planning to take. You should also figure out what equations
you’ll need to determine where the net and ring should be placed for each
part of the act.
As far as I can tell, this looks like a simple projectile-motion problem.
Develop the equations and models to predict the maximum vertical and
horizontal displacements at different angles. That will allow us to make recommendations
based on our tests. Let’s perform tests for launching at 20º,
40º, and 60º. For each angle, we need to recommend the placement of the
ring and of the net.

For each part of the act, I think we should provide a set of equations
and a working model of the act. We want to make sure that the equations
will give the correct placement of the net for any angle they start with, given
the initial speed. Pay special attention to answering the following questions:
• Exactly where should the net be placed?
• Where should the center of the flaming hoop be placed?
As I said at the meeting, it has been a great year at this company thanks to
all of you.
