Suppose a spaceship has the mass of a typical ocean cruise ship, then it can be assumed that it has a mass of 3.3 × 108 kg. Consider the kinetic energy required at 17 % of the speed of light. If energy to get a spaceship to cruising speed is generated using matter-antimatter annihilation, what mass of antimatter in kg is required?

Hint: Matter-antimatter annihilation converts an entire mass of matter and antimatter into pure energy with no loss.

Suppose such a ship has a mass of 2.00×106kg and carries a mass of fuel equal to 3 % of its mass, or 3.00×10^4kg of matter, and an equal mass of antimatter. What is the final speed of the ship, assuming it starts from rest if all energy released in the matter-antimatter annihilation is transformed into the kinetic energy of the ship? Express your answer with the appropriate units.
