This program solves the differential equations governing the flight of a baseball based on the model developed by Robert Adair in his book "The Physics of Baseball". (Details will appear elsewhere.) It was first developed to verify the length of what was probably a 525 foot home run by J.D. Drew.
The program enforces the following limits:
Wind speed must be between -20 and +20 mph. Speed of the batted ball must be positive and less than 140 mph. Angle of the batted ball must be between 0 and 90 degrees. These parameter ranges are enforced by the program. A warning is issued if the total of the ball speed and wind speed exceeds 150 mph because the coefficients in use may not be reliable in that situation.
Common problems such as lack of sufficient colors or poor color mapping are to be expected based on my tests. Feedback or suggestions on colors that might map better, or any other problems, are solicited.
Note that you must hit the 'Enter' key after changing one of the parameters before it will take effect.
A yellow dot shows that the trajectory hit the fence in use when the calculation was done. The tick marks are made every second on the most recent trajectory. Distances printed are rounded to the nearest foot and are not that accurate.

My other college baseball material is on a "just the facts" web page, all of which is a sidelight to my usual work of doing theoretical nuclear physics.
