4. a) Answer both of the following questions regarding Special Relativity: An astronaut leaves their twin behind on Earth and departs on a journey on a spacecraft travelling at a speed of 0.840c. After 40.0 years pass on Earth, the astronaut returns to Earth to find that their age is now different from their twin. How old is the astronaut upon returning to Earth? b) A muon, travelling at a speed of 0.999c, travels a distance of 10.0 km from the Earth's atmosphere to a muon detector on the surface of Earth (these distances are considered from Earth's perspective). How far does the muon travel from its own perspective? 4. a) Answer both of the following questions regarding Special Relativity: An astronaut leaves their twin behind on Earth and departs on a journey on a spacecraft travelling at a speed of 0.840c.
