The astronauts disagree My Notes Ask Your (a) How much time passes on the astronauts' clocks? (No Response) years (b) What is the distance to Alpha Centauri as measured by the astronauts?

Explanation / Answer

Given,

v = 0.914 c ;

a)We know that

gamma = 1/sqrt(1 - v^2/c^2)

gamma = 1/sqrt(1 - 0.914^2c^2/c^2) = 2.465

t' = t/gamma = 4.6/2.465 = 1.866

Hence, t' = 1.866 years

b)d' = d/gamma

d' = 4.2/2.465 = 1.704 ly

Hence, d' = 1.704 ly
