Relativistic Velocity Addition
Two spaceships, A and B, are moving along the same line in opposite directions. Relative to an inertial reference frame, spaceship A has a speed of 0.6c and spaceship B has a speed of 0.8c. What is the velocity of spaceship B as measured from the reference frame of spaceship A?
A
1.4c in the direction opposite to A’s motion
B
0.946c in the direction opposite to A’s motion
C
0.714c in the direction opposite to A’s motion
D
0.2c in the direction opposite to A’s motion
