Paragraph : A spaceship traveling east flies directly over the head of an inertial observer who is at rest on the Earth's surface. The speed of the spaceship can be found from this relationship: `sqrt(1-v^(2)//c^(2))=1//2`.
The pilot fires an ion gun that propels ions from the space ship at `1.0xx10^(8)m//s` relative to the ship. What is the speed of the ions as measured by the Earth observer?

A

`1.0xx10^(8)m//s`

B

`2.4xx10^(8)m//s`

C
