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.
