calculus
posted by marlyn .
a bomb is drooped from an airplane at an altitude of 14,400 feet. how long will it take to reach the ground? (Because of the motionof the plane, the fall will not be vertical, but the time will be the same as that for a vertical fall.) the plane is moving at 600 miles per hour. How far will the bomb move more horizontally after it is released from the plane?

Calculus? You have to be kidding.
h=1/2 g t^2
solve for t
horizontaldistance=vi*time
