Aspecial vehicle of length 50 m is designed to take passengers at extremely high speeds between different places on earth.
(a) how fast must the vehicle move (in units of c) so that its length measured by an earthbound observer is 49 m?
(b) refer to part (a). if the vehicle carries passengers a distance of 6,000 km, by how much will the travel time measured by a clock on the vehicle differ from the time measured by an earth-based clock? in other words, what is δt vehicle − δt earth ?
