It is year 2120 and we have figure out a propulsion system that allows spaceships travel at velocities as high as v = 0.87c. A first expedition to Alpha Centauri (the nearest planetary system) is being planned. Alpha Centauri is 4.3 ly away. Answer the following 5 questions below asking you about the details of this expedition. Question 10 2 pts Assuming a constant velocity of v=0.87c, how long would the trip to Alpha Centauri take as observed by the ground control team here on Earth? Give your answer in years

Question 11 2 pts How long would the trip to Alpha Centauri take as observed by the astronauts in the spaceship? Give your answer in years. Question 12 2 pts What would be the distance between Earth and Alpha Centauri as observed by the astronauts in the spaceship? Give your answer in ly.

Question 13 2 pts If the mass of the spaceship (including the astronauts) is m = 10^4 kg, what would be its rest energy. 3 x 10^12 Joules O 9 x 10^9 Joules O 3 x 10^20 Joules O 9 x 10^20 Joules O 3x 10^9 Joules 09x 10^12 Joules

Question 14 2 pts What would be the total energy of the spaceship (m = 10^4 kg) when moving at v = 0.75c as observed by Earth? O 18 x 10^12 Joules 18 x 10^20 Joules 1.5 x 10^20 Joules O 4.5 x 10^12 Joules O 4.5 x 10^20 Joules O 9 x 10^9 Joules
