A spaceship and its occupants have a total mass of 1.6×105 kg. The occupants would like to travel to a star that is 22 light-years away at a speed of 0.64c. To accelerate, the engine of the spaceship changes mass directly to energy.
- Estimate how much mass will be converted to energy to accelerate the spaceship to this speed?
Express your answer to two significant figures and include the appropriate units.
- Assuming the acceleration is rapid, so the speed for the entire trip can be taken to be 0.64c, determine how long the trip will take according to the astronauts on board.
Express your answer using two significant figures.

Suppose we have a spaceship about the size of a typical ocean cruise ship today, which means it has a mass of about 140 million kilograms, and we want to accelerate the ship to a speed of 11 % of the speed of light. Suppose you want to generate the energy to get it to cruising speed using matter-antimatter annihilation. How much antimatter would you need to produce and take on the ship? Express your answer using two significant figures....
