The passenger of example slept with his head towards the engine and feet towardsthe guard's coach. If he measured 6 ft in the train frame, how tall is he in the ground frame ?

Answer»

Solution :In the ground frame, the passanger is moving with a velocity c / 10 . His length is thus contacterd. Thelength measured in the train frame is the rest length of the passenger as the passenger is at rest in the train. Thus , his length in the ground frame is
` L' = 6 FT (SQRT 1 - (1 / 10 )^(2)) =6 ft (sqrt 99 / 100 ) = 5 FEET 11.6 inches`.
