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
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?

A muon has an average life time t_0 = 2.2μs from Earth's frame of referance. Needed distance for them to be found on earth surface is 6Km . What is the average life time of muon from it's own frame of referance if they are travelling with an speed of 2.978×108 m/s ?
Imagine yourself as an astronaut being paid according to the time you spend traveling in space. You take a long voyage traveling at a speed near that of light. Upon your return to Earth, you’re asked how you’d like to be paid: To maximize your paycheck, which clock should you choose?
Group of answer choices
Either of the clocks should indicate the same time
It's hard to decide as the spaceship's speed is to be mentioned specifically in the problem.
According to the time elapsed on the spaceship's clock
According to the time elapsed on a clock on Earth
