Question
A spaceship travels at $0.750 c$ relative to Earth. If the spaceship fires a small rocket in the forward direction, how fast (relative to the ship) must it be fired for it to travel at $0.950 c$ relative to Earth?
Step 1
The spaceship is moving at a speed of $0.750c$ relative to Earth. The spaceship then fires a rocket in the forward direction. We want to find out how fast the rocket must be fired relative to the spaceship so that it travels at a speed of $0.950c$ relative to Show more…

A large spaceship is passing Earth at $0.750 c$. Inside it is a medium-sized $\mathrm{cH}$ spaceship going at $0.750 \mathrm{c}$ relative to the large spaceship. And inside the medium ship is a small one going at $0.750 c$ relative to the medium one. What's the speed of the small ship relative to Earth?
A spaceship is moving away from Earth at 0.900$c$ when it fires a small rocket in the forward direction at 0.500$c$ relative to the spaceship. Calculate the rocket's speed relative to Earth.
