Suppose we have a spaceship about the size of a typical ocean cruise ship today, which means it has a mass of about 110 million kilograms, and we want to accelerate the ship to a speed of 9% of the speed of light. Part A How much energy would be required? (Hint: You can find the answer simply by calculațing the kinetic energy of the ship when it reaches its cruising speed; because 9% of the speed of light is still small compared to the speed of light, you can use this formula: kinetic energy = 2 xm x v2 Express your answer to two significant figures and include the appropriate units. E = Value Units Submit Request Answer Part B How does your answer compare to total world energy use at present, which is about 5 x 104 joules per year? Express your answer as a percentage using two significant figures. ΑΣφ ? Espaceship Eworld energy use Submit Request Answer • Part C The typical cost of energy today is roughly 5 cents per 1 million joules. Using this price, how much would it cost to generate the energy needed by this spaceship? Express your answer in dollars to two significant figures. , ΑΣΦ ? cost =
