18. Two spaceships are traveling in the same direction. With respect to an inertial frame of reference, spaceship A has a speed of 0.900c. With respect to the same inertial frame, spaceship B has a speed of 0.500c. Find the speed vAB of spaceship A relative to spaceship B.

Answer:

[tex]v_{A} -v_{B}=v_{AB}\\v_{AB} =0.9c-0.5c\\v_{AB}=0.4c[/tex]

Explanation:

Because the spaceships are traveling in the same direction, you should subtract the speed of spaceship A from the speed of spaceship B in order to calculate [tex]v_{AB}[/tex].
