False
If you were traveling inside a spaceship at a speed of c/2 relative to Earth and you fired a laser beam in the direction of the spaceship’s motion, the light from the laser would travel at a speed of 2c relative to Earth.
Group of answer choices
True
False
An astronaut is traveling in a spacecraft at a speed of 0.8 times the speed of light (0.8c) relative to an observer on Earth. If the astronaut spends 5 years according to their own onboard clock, how much time will have passed on Earth when they return?

While on board a starship, you intercept signals from four shuttle craft that are moving either directly toward or directly away from you.The signals have the same proper frequency f0.The speed and direction (both relative to you) of the shuttle craft are (a) 0.3c toward, (b) 0.6c toward, (c) 0.3c away, and (d) 0.6c away. Rank the shuttle craft according to the frequency you receive, greatest first.

You have been hired as an expert witness in the future by an attorney representing the driver of a spacecraft. The driver is accused of exceeding the galactic speed limit of 0.700c relative to the Earth while being chased by a galactic police spacecraft. The driver claims he is innocent, that his speed was well below that limit. You have been provided with the following data: the police spacecraft was traveling at 0.600c while chasing the driver and a technician on the police spacecraft measured the suspected spacecraft as traveling at 0.300c relative to the police spacecraft. What advice should you give the attorney?

Imagine two civilizations from different planets that have started an intergalactic war. During a space battle, a missile is shot from spaceship one toward spaceship two. The missile leaves the spaceship one at 0.970c (in spaceship one's reference frame) and approaches spaceship two at 0.749c (in spaceship two's reference frame). What is the relative velocity of the two spaceships in units of c?
Hint: keep in mind that the two spaceships are approaching each other.
