A cargo plane is flying horizontally at an altitude of 10.2 km with a speed of 970 km/h when a large crate falls out of the rear loading ramp. (Ignore any effects due to air resistance.) How far is the crate from the aircraft when the crate hits the ground, assuming that the plane continues to fly with the same velocity?
