The pilot of an airplane traveling 250km/h wants to drop supplies to flood victims isolated on a patch of land 190m below.
physics PLEASE HELP! -
how long to drop 190 m?
190 = (1/2) (9.81)t^2
t = 6.22 seconds
how far horizontal in 6.22 s ?
(250,000 m/3600 s)6.22 s = 432 meters
so drop 432 meters before reaching target zenith
