Earth's neighboring galaxy, the Andromeda Galaxy, is a distance of 2.54 × 10 7 2.54×107 light-years from Earth. If the lifetime of a human is taken to be 80.0 80.0 years, a spaceship would need to achieve some minimum speed v min vmin to deliver a living human being to this galaxy. How close to the speed of light would this minimum speed be? Express your answer as the difference between v min vmin and the speed of light c c .

The difference between v and the speed of light is 0.00149 m/s

Explanation:

The time dilation is equal to:

The difference between v and the speed of light is equal:

c - v = 3x10⁸*(1-0.99999999999504) = 0.00149 m/s

  distance on the y-axis and time on the x-axis.

explanation:

the instantaneous velocity = change in position/time taken

the slope of the graph should give instantaneous velocity.

  slope of a graph = change in value of y -axis / change in values of x -axis

  comparing both the equations

    change in value of y -axis = change in position

  change in values of x -axis = time taken

so position values should be on the y axis and time values should be on the x axis.

distance on the y-axis and time on the x-axis.
