-An astronaut is resting on a bed inclined at an angle above the floor of a spaceship, as shown in Figure 29-1. 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) is greater than the angle observed by the astronaut. 
B) is the same as the angle observed by the astronaut. 
C) is smaller than the angle observed by the astronaut. 
D) could be greater or smaller than the angle observed by the astronaut depending on the actual speed of the craft.

Quizplus · Accepted Answer

The angle is greater than the angle observed by the astronaut because the spaceship is moving to the right with a speed approaching c, which causes the bed to appear to be tilted more to the right from the observer's point of view.
