A bomb is dropped from a plane flying at 4000 meters. The plane is flying at 80 m/s. How far, in a horizontal direction, did the bomb hit the ground?

A pilot drops a bomb from a plane flying
horizontally at a constant speed. Neglecting
air resistance, when the bomb hits the ground
the horizontal location of the plane will
A) be behind the bomb.
B) be over the bomb
C) depend on the speed of the plane when
the bomb was released.
D) be in front of the bomb

h = ho.d - o.5g*t^2 = 0
4000 - 4.9t^2 = 0
-4.9t^2 = -4000
t^2 = 816.3
Tf = 28.6 s. = Fall time or time in flight.

Dx = Hor = 80m/s * 28.6s = 2286 m.
