An armada of spaceships (at rest in frame A), of proper length Lo =1.10ly (ly is a unit of distance equal to the distance that light travels in a year), is moving in the +x direction at a speed v = 0.600 c as measured in the Earth frame. A small messenger spaceship B (at rest in frame B) is sent from the tip of the armada toward the tail of the armada. It's moving in the opposite direction relative to the armada (-x direction) with u, =-0.750c as measured in the frame of the armada, A. Spaceship B flies by the entire armada from tip to tail. a. What is the speed of spaceship B relative to the Earth frame, u, b. In frame A, how long does it take for spaceship B to move from the tip of the armada to the ? tail of the armada?
