•• A ladder 5.0 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 3.0 m from the wall, and the top of the ladder is 4.0 m above the floor. The spaceship moves past the Earth with a speed of 0.90c 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.

Step-by-Step Solution:

Solution 33 P:

Step 1 of 1:-

a)

Here, we have to find the angle that the ladder makes with the floor seen by the observer.

Given that,

The length of my friend’s spaceship in his frame is,
