An airplane traveling 1007 m above the ocean at 150 km/h is going to drop a box of supplies to shipwrecked victims below.
(a) How many seconds before the plane is directly overhead should the box be dropped?(b) What is the horizontal distance between the plane and the victims when the box is dropped?

physics 
bobpursley,
change velocity to m/s
how long does it take to fall 1007?
h=1/2 g t^2 solve for t.
then, what horizonal distance is covered in t seconds: distance=V*t calculate distance.
