Question

10) An astronaut is resting on a bed inclined at an angle above the floor of a spaceship. From the point of view of an observer who sees the spaceship moving to the right with a speed approaching c, the angle the bed makes with the floor

A) could be greater or smaller than the angle observed by the astronaut depending on the actual speed of the craft.

B) is greater than the angle observed by the astronaut.

C) is smaller than the angle observed by the astronaut.

D) is the same as the angle observed by the astronaut.

Explanation / Answer

Lengths contract along the direction of relative motion. This will cause x to contract, while y is constant.

Therefore, the moving observer will measure a larger theta than the astronaut
