Answer:
The velocity of the ions relative to the earth observer is ![v = 0.63 c](https://tex.z-dn.net/?f=v%20%3D%200.63%20c)
Explanation:
From the question we are told that
The speed of the alien ship is ![v_a = 0.3c](https://tex.z-dn.net/?f=v_a%20%20%3D%200.3c)
The speed of the iron gun is ![v_g = 0.4c](https://tex.z-dn.net/?f=v_g%20%20%3D%20%200.4c)
The motion of the ions relative to the earths observer can be mathematically represented as
![v = \frac{v_a + v_g}{[\frac{1+ v_av_g}{c^2} ]}](https://tex.z-dn.net/?f=v%20%20%3D%20%20%5Cfrac%7Bv_a%20%2B%20v_g%7D%7B%5B%5Cfrac%7B1%2B%20v_av_g%7D%7Bc%5E2%7D%20%5D%7D)
substituting values
![v = \frac{ 0.3c + 0.4c}{[\frac{1+ 0.3c * 0.4c}{c^2} ]}](https://tex.z-dn.net/?f=v%20%20%3D%20%20%5Cfrac%7B%200.3c%20%2B%200.4c%7D%7B%5B%5Cfrac%7B1%2B%200.3c%20%2A%200.4c%7D%7Bc%5E2%7D%20%5D%7D)
=> ![v = 0.63 c](https://tex.z-dn.net/?f=v%20%3D%200.63%20c)
