A magnetic rail gun is used to shoot a packet of metal from the new asteroid mining facility towards a capture facility on the moon. The package is shot at a velocity of 0.82c. How fast does the package appear to be moving to a nearby spacecraft that is travelling in the same direction at a speed of 0.67c?
since they are going in the same direction? is just simply a vector addition
0.82 c + 0.67c?
