Cruise Ship Enery. Suppose we have a spaceship about the size of a typical ocean cruise ship today, which means it has a mass of about l00 million kilograms, and we want to accelerate the ship to a speed of 10% of the speed of light. a. How Inuch energy would be required? (Hint; You can find the answer simply by calculating the kinetic energy of the ship when it reaches its cruising speed; because 10% of the speed of light is still small compared to the speed of light, you can use thsi formula kinetic energy = 1/2 x m x v2) b. How does your answer coInpare to total world energy use 5 x 1022 Joules? c. The typical cost of energy today is roughly 5¢ per 1 million joules. At this price, how much would it cost to generate the energy needed by this spaceship?
