A spaceship is moving in a straight line at a speed of 08 c

A spaceship is moving in a straight line at a speed of 0.8 c (relative to Earth). It launches a missile that moves away from the spaceship (traveling in the same direction as the spaceship) at a speed of 0.6 c. Relative to Earth, the speed of the missile is A) greater than c and less than 1.4 c C) 1.4 c. B) greater than 0.8 c and less than c. D) c.

v=(.8c+.6c)/(1+.8*.6) = .946c
