Hi Ether,

Sorry for the illegible chart.

Launch angle- 60deg
Init. speed- 22 f/s
Cd - 0.5
Density- 0.074 lb/m^3
Cd is a calculated function; see U of IL spreadsheet: http://baseball.physics.illinois.edu...culator-v2.xls

I haven't worked through the calculations completely and still need to adjust Re (spreadsheet is 100 mph,147 f/s)
