1. An alien starship is 0.20 lightyears from Earth and traveling at 0.70c, as observed from Earth. This ship sends out a smaller scout ship to see if the inhabitants of Earth are friendly. This scout ship travels at 0.90c as seen from the starship and has a mass of 350,000 kg. a) Determine the velocity of the scout ship as seen from an observer on Earth. b) At the time of the launch of the scout ship, what is the distance to Earth as measured by the aliens abroad the main ship, and c) and the scout ship?. d) Find the time it takes the scout ship to get to Earth as seen by both Earth and main ship observers. e) What is the kinetic energy of scout ship from the reference frame of the Earth?
