The Carry of a Fly Ball

The ball hits ground level at a distance of D 0 = 571 ft from home plate. In this case, the "carry" R = D/D 0 = 397/571 = 0.695. That is, the aerodynamic effect of lift and drag result in a distance that is about 70% of the vacuum distance. This calculation was done for an air density appropriate for sea level and 60 o F.
