Question:
An observer on Earth notes that an astronaut on a spaceship puts in a 4-hour shift at the controls of the spaceship. How long is this shift as measured by the astronaut himself, if the spaceship is moving with a velocity of 0.8c relative to the Earth? (See table 20.1. Be careful which observer measures the proper time?)
