A space ship travels with velocity of 1.5 x 10^8 m/s. One person is sitting inside space ship with a stick of 2 m in his hand. And one observer is looking at space ship from ground when the space ship started from rest, And this time its 9 am in his watch. A) After 2 hours, What will be the time in the watch of Pilot in in space ship? B) What will be length of stick observed by observer? C) And if the mass of Pilot at ground is 80 kg then how much it will be in the space ship when it is moving with velocity of 1.5 x 10^8 m/s?
