    Purpose of use
    Calculating initial velocity and launch angle for a football punter from game film to help fine tune practice goals. Confirmed initial assessment that ball was being kicked at too high a launch angle and was losing potential distance.

    Would be helpful to include drag or air resistance.

    where does the 8 in the denominator of the height equation come from? Besides that, very helpful with good equations.

    We have added another formula in h.

    This is completely not accurate.
    A baseball hit at 103 mph at 28.3* above the horizantle will travel about 403 feet with an average apex of 91ft high.

    Your equations are correct, but not applied properly. A good source of comparison is hittrackeronline.com . Even given the relations between humidity, temperature, ball rotation, etc. you are not even close. AN example of the error: you cannot hit a baseball only 45MPH at 70* and expect it to go 450feet.
