Re: Calculating Angle to fire at

Here's a "quick and dirty" Excel spreadsheet that allows the user to vary speed, angle, height, drag coefficient, and for the Mars version of AimHigh (special feature for Dave Lavery ): air density and gravity.

The algorithm is based on the white paper found here:

http://wps.aw.com/wps/media/objects/...cs/topic01.pdf

I made sure the integration gave accurate answers for some test cases (verify max height for vertical shot with zero drag coefficent, etc.).

The user should be able to perform some "sensitivity analyses" on parameters like speed, drag coefficient, etc. to get some idea of how the trajectory is affected by changes in the various parameters.

You can answer: How much further does a new (low drag) ball fly in Colorado than a beat-up (high drag) ball at the Florida Regional?
