QUESTION:

Problem 70GP

A spaceship and its occupants have a total mass of 160.000 Kg. The occupants would like to travel to a star that is 35 light-years away at a speed of 0.70c. To accelerate, the engine of the spaceship changes mass directly to energy, (a) Estimate how much mass will be converted to energy to accelerate the spaceship to this speed (b) Assuming the acceleration is rapid, so the speed for the entire trip can be taken to be 0.70c. determine how long the trip will take according to the astronauts on board.
