A spaceship, traveling at WARP 1/2 away from the Earth, launches a shuttle moving away from the ship at c/2 (c/2 seen from the ship).

Classically one expects to see the shuttle moving at c from the Earth, but relativistically what speed do we expect seen from the Earth? A) 0.9c
B) 0.5c
C) 0.8c
D) 0.7c
E) 0.6c

Question 2

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) 1.2c
B) c
C) 0.6c
D) 0
E) none of the above
