You’re in an airplane that flies horizontally with speed 1000 km/h (280 m/s) when an engine falls off. ignore air resistance and assume it takes 30 s for the engine to hit the ground. (a) show that the airplane is 4.5 km high. (b) show that the horizontal distance that the aircraft engine moves during its fall is 8400 m. (c) if the airplane somehow continues to fly as if nothing had happened, where is the engine relative to the air- plane at the moment the engine hits the ground
