Question
Two spaceships are moving directly toward each other with a relative velocity of $0.90 c$. If an astronaut measures the length of his own spaceship to be $30.0 \mathrm{~m}$, how long is the spaceship as measured by an astronaut in the other ship?
Step 1
First, we need to find the Lorentz factor, which is given by the formula: γ = 1 / sqrt(1 - v^2/c^2), where v is the relative velocity and c is the speed of light. Show more…

A spaceship is moving at a constant velocity of $0.70 c$ relative to an Earth observer. The Earth observer measures the length of the spaceship to be $40.0 \mathrm{m}$. How long is the spaceship as measured by its pilot?
Two identical spaceships with proper lengths of 175 m are launched from Earth. Spaceship A is launched in one direction at 0.500c and spaceship B is launched in the opposite direction at 0.750c. (a) What is the speed of spaceship B relative to spaceship A? (b) What is the length of spaceship A as measured by astronauts on spaceship B ?
