A ladder 5.6 m long leans against a wall inside a spaceship. From the point of view of a person on the ship, the base of the ladder is 2.6 m from the wall, and the top of the ladder is 5.0 m above the floor. The spaceship moves past the Earth with a speed of 0.82c in a direction parallel to the floor of the ship. Find the angle the ladder makes with the floor, as seen by an observer on Earth.
