Calculate the energy needed (in J) to accelerate a spaceship of mass 13,000 kg to a speed of 0.32c for intergalactic space exploration. Compare this with a projected annual energy usage on Earth of $10^{21}$ J. (Enter your answer as a percentage of Earth's energy usage.)

Step 1
This is a difficult task as intergalactic space exploration is currently beyond our technological capabilities. However, we can make an estimate based on the energy requirements for current space exploration missions. According to NASA, the energy required for a Show more…

Calculate the kinetic energy that the earth has because of its rotation about its own axis and its motion around the sun. Assume that the earth orbits the sun in a circular path. For comparison, the total energy used by the United States in a year is about 1.1 J.
