0 + 4.9t^2 = 10,000,

t^2 = 2041,

t = Tf = 45.2 s. = Fall time = Time in

flight.

Dx = Xo * Tf = 300 m/s * 45.2 s. = 13,553 Ft.= Dist. it should be released from target.

**Henry**, Tuesday, December 20, 2011 at 9:31pmCorrection:

d = Vo*t + 0.5g*t^2 = 10,000 Ft.

0 + 16t^2 = 10,000,

t^2 = 625,

t = 25 s.

X0=300 mi/h * 1h/3600 s. = .0833 mi/s.

Dx = 0.08333 mi/s * 25s = 2.083 mi =

3333 m.
