Cruise Ship Energy. Suppose we have a spaceship about the sizeof a typical ocean cruise
Chapter 13, Problem 49(choose chapter or problem)
Cruise Ship Energy. Suppose we have a spaceship about the sizeof a typical ocean cruise ship today, which means it has a massof about 100 million kilograms, and we want to accelerate theship to a speed of 10% of the speed of light.a. How much energy would be required? (Hint: You can findthe answer simply by calculating the kinetic energy ofthe ship when it reaches its cruising speed; because 10%of the speed of light is still small compared to the speedof light, you can use the formula that tells us that kinetic)b. How does your answer compare to total world energy use atpresent, which is about joules per year?c. Suppose the cost of energy is 3 per 1 million joules. Usingthis price, how much would it cost to generate the energyneeded by this spaceship?
