A spaceship is moving directly toward a planet at a speed of 70% of the light speed.When the spaceship is 3x10^8 m from the planet, a pulse of light is emitted by the spaceship from an outside observer,how long does it take the light pulse to travel from the spaceship to the planet?

Dear student,Despite the fact that the spaceship is approaching the planet at a speed of 70% of speed of light, occupants of the ship will still measure the speed of light to be c. time=3×1083×108=1secRegards
