An airplane flies horizontally with a speed of 300 m/s at an altitude of 400 m. Assume the ground is level. What horizontal distance from a target must the pilot release a bomb so as to hit the target? I know the answer is 2.7 km because it is or a review packet prior to a big test however, I do not know how my teacher got the problem. Is it x=1/2at^2+vot? I am confused!
