To calculate the time experienced by the astronauts on the ship, we can use the time dilation formula:
t' = t / √(1 - (v^2/c^2))
Where:
t' is the time experienced by the astronauts on the ship
t is the time measured on Earth
v is the velocity of the spaceship relative to the speed of light (0.99c)
c is the speed of light (299,792,458 m/s)
Plugging in the given values, we have:
t' = 10 / √(1 - (0.99^2))
= 10 / √(1 - 0.9801)
= 10 / √(0.0199)
≈ 10 / 0.141
≈ 70.92 years
Therefore, the astronauts on the ship would experience approximately 70.92 years.
To calculate the distance traveled by the spaceship, we can use the equation:
d = v * t'
where:
d is the distance traveled by the spaceship
v is the velocity of the spaceship relative to the speed of light (0.99c)
t' is the time experienced by the astronauts on the ship (70.92 years)
Plugging in the given values, we have:
d = 0.99c * 70.92 years
= 0.99 * 299,792,458 m/s * 70.92 * 365.25 * 24 * 60 * 60 seconds
≈ 2.089 * 10^16 meters
Therefore, the spaceship would have traveled approximately 2.089 * 10^16 meters.
