Hi there
Can members please review my understanding of the problem.
1. The problem
A star is 522 light years away from Earth. Imagine that the spacecraft was able to travel to the star at a speed pf 0.9999c
a) How long does the trip take, as observed from Earth?
b) How mauch time has passed on the spacecraft s clock, as seen from Earth?
c) How much time has passed on Earths clock, as seen from the spacecraft ?
Part a) t = d/v 522 light years /0.9999c = 522.05 years (I think that this okay)
Part b) to = 522.05 √ 1 – (0.9999c)^2
=7.38 years
=7 years 139 days (not sure if I need to convert to years and days or leave in years?)
Part c) This is the part that I am difficulty with? I think that the time on Earth, as observed by the spacecraft would be as follows:
tv = 7.38/ √ 1 – (0.9999c)^2
=??
As above
