Scoreboard
This page shows Wisconsin Professional Surveyor Problem Corner challenges, select user-submitted solutions,
and a running count of who submitted solutions.
Although many of these problems are more easily solved using computers, demonstration of mental rather than software dexterity is preferred. Software can be used for checks or repetitious calculations (eg, spreadsheet for iterative solutions) but the main calculations should be manual. And we all know the importance of math checks.
You can either scan your solution and email it to me at gmahun@matcmadison.edu or jmahun@yahoo.com or snail-mail to me at 567 Prestige Court, Edgerton, WI 53534.
A scoring scheme (see below) will be used to determine the annual top three solvers amongst all submitters.
To see a selected submitted solution click on the underlined name; ditto for the problem statement. You need a pdf viewer installed in your browser or Acrobat Reader on your computer.
Since the answer and submitters are announced in the following issue of the Wisconsin Professional Surveyor, deadline for submission will be when that issue goes to the publisher.

Since the December issue of the Wisconsin Professional Surveyor comes out just before the Annual Institute and
solutions start trickling in January, the annual total will be based on the Dec-Mar-Jun-Sep issues sequence. The annual winner
will be announced in the following Dec issue.

Correct coordinates with the right touch of incentive to make sure the crew doesn't have any more of these problems.

Even though he was suffering a bout of Blastomycosis (which caused him to miss the Institute in who knows how many years),
Dave came up with the correct solution.

Mike was on the right track but since he did it meticulously by long hand it looks like he stopped just before he got to the right combination of distances. |

According to Burt: "I solved this problem by getting a hold of a 10 gallon jug of wine and proceeding with a trial
and error method. It took five or six attempts, but we sure had fun doing it!!"
Unfortunately, Burt was off a little but we admire his initiative. |

Set up a spreadsheet to get the solution. Brian wrote that "My little daughter distracted me, I should have sent this
in yesterday afternoon." Children are a joy ... and a good excuse.

It took Norm a few times, but he eventually came up with the right answer. He
was docked a few points for his earlier attempt(s).

Tony didn't get his June WPS in the mail until 6 Jul whereupon he promptly, and correctly, solved the problem. If this
"competition" heats up, we're going to have to make allowances for US Mail speed.

Typical of Mike, nicely developed computations leading to a correct solution.

As
I checked over the the first solution received, I discovered that in order to simplify the problem I wound up over simplifying part of it. I stated at the end of the problem to assume the football's velocity was
constant. This is neither true nor a reasonable assumption. The ball immediately begins decelerating when it leaves Rodgers'
hand until it reaches the trajectory's apex. It then begins to accelerate due to gravity and eventually reaches Driver
at the same velocity at which Rodgers threw it.
Since it was my mistake in the problem statement, I will take that
into account where applicable when granting bonus points.
