Thank you.
You are now in 20 years old. You are disappointed with the current situation. So, you decide to leave to the future of Earth. You plan a space journey for 5 years(go in 2.5 years and back in 2.5 years.) with a constant speed v relative to Earth. If you wish to reach the Earth after 100 years when you are 25 years old, how fast the speed, v you need to set for your spaceship? (Give your answer in 5 significant figures)

At t=0, an alien spaceship passes by the earth: let this be event A. At t=13 min (according to synchronized clocks on earth and Mars), the spaceship passes by Mars, which is 5 light-minutes from earth at the time: let this be event B. Radar tracking indicates that the spaceship moves at a constant velocity between earth and Mars. Just after the ship passes earth, people on earth launch a probe whose purpose is to catch up with and investigate the spaceship. This probe accelerates away from earth, moving slowly at first, but moving faster and faster as time passes, eventually catching up with and passing the alien ship just as it passes Mars. In all parts of this problem, you can ignore the effects of gravity and the relative motion of earth and Mars (which are small) and treat earth and Mars as if they were both at rest in the inertial reference frame of the solar system. Also assume that both the probe and the alien spacecraft carry clocks. 1. Draw a quantitatively accurate…
