You're in an airplane that flies horizontally with speed 1000lkm/h (280 m/s) when an engine falls off. Neglecting air resistance, 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 falls is 8400m.
c. if the airplane somehow continues to fly as if nothing had happened, where is the engine relative to the airplane at the moment the engine hits the ground?
