Two spaceships are traveling through space at 0.6c relative to the Earth. If the ships are headed directly toward each other, what is their approach velocity, as measured by a person on either craft?
A) 0
B) c
C) 0.6c
D) 1.2c
E) none of the above

Question

Quizplus · Accepted Answer

The approach velocity of the two spaceships, as measured by a person on either craft, cannot be simply added because velocities nearing the speed of light must be calculated using the relativistic velocity addition formula. This formula ensures that the resulting velocity does not exceed the speed of light (c). Therefore, the correct answer is not given by the options provided, making "none of the above" the correct choice.
