Lawson Chapman · Answer 1

Given the speed of the 0.500c, the spacecraft is spherical.

Explanation:

The length of an object is contracted in the direction of the motion. It can be visualize that if a spherical body is contracted along a particular axial direction then the shape of the spherical body is seem to be in shape of a pillow, similarly the spherical spacecraft moves away and seems to be contracted along the direction of motion, so it becomes a round shape flattened along the direction of motion.
