Question

An observer on Earth sees spaceship 1 fly by at 0.80c. 6.0 years later, the observer on Earth sees spaceship 2 fly by at 0.80c, traveling in the same direction as the first. Both spaceships continue to travel with constant velocities. An observer in spaceship 1 observes Earth to pass spaceship 2 ____ years after Earth passed spaceship 1.

Answer 1

Answer:

$t_2=10$

Explanation:

From the question we are told that:

Velocity of both spaceships $V=0.8c$

Time $t_1=6$

Generally the equation for time of spaceship 2 through earth is mathematically given by

$t_2=\frac{t_1}{\sqrt{1-v^2}}$

$t_2=\frac{6}{\sqrt{1-0.8^2}}$

$t_2=10$
