An airplane travelling horizontally at 406 km/h at a height of 2 km releases a bomb. How far ahead (to the nearest meter) from the release point does the bomb strike the ground?
There is no horizontal component of acceleration, due to gravity.
Bomb speed, at release, is 406 km/h =
If time between release and strike is t sec, horizontal distance of the target is
Vertical distance traveled is
2 km =
t = 20.193s, nearly..
x = 2.2773 km = 2277 meter, nearly.
