1. A spaceship A moves east along the x axis with a speed of 0.80c and a spaceship B moves west toward the spaceship A with a speed of 0.70c as measured by an observer on the Earth. Calculate the speed of the spaceship A measured by an observer in the spaceship B in terms of c.
Spaceship A is moving toward the Earth at 0.80c, and spaceship B is moving away from Earth at the same speed, according to observers on a distant planet. At the same moment, very bright lights are turned on at the front of spaceship A and on the back of spaceship B. The light from a)Spaceship A reaches the planet before the light from spaceship B. b)both ships reaches the planet at the same time. b)either ship could reach the planet first, but there's no way to tell in advance. d) Spaceship B reaches the planet before the light from spaceship A.

* Sophie and Frieda are twins. They plan a trip to planet X which is 54 light years from Earth. They both leave Earth on their 30th birthday, but on different spacecraft. Sophie takes a spacecraft that travels at .99c, and Frieda takes a spacecraft that travels at .95c. As soon as Frieda arrives she is met at the terminal by Sophie (who was waiting there for her since she had arrived!). What are each of their biological ages (to the nearest 0.1 year) at this meeting? Earth and planet X are in the same (stationary) frame of reference here. A light year is 9.47x1015 m (but using meters will be awkward here)
A spaceship carrying a light clock moves at a speed of 0.6c relative to an observer on Earth.
