A cargo plane is flying horizontally at an altitude of 20.0 km with a speed of 888 km/h when a large crate falls out of the rear loading ramp. (Ignore any effects due to air resistance).
A. How long does it take the crate to hit the ground?
B. How far horizontally is the crate from the point where it fell off when it hits the ground?
C. 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?
