Object accelerated at one G for one year

[Supersiiix4]

Hello, this is my first post on Physics Forums.


If an object at rest is accelerated at 1G (9.81m/s^2) for 1 year (3.15569 x 10^7 Seconds), using the
equation V= Vo +AT

V=( 9.81 m/s^2) x (3.15569 x 10^7 Seconds) = 10,000,012.1 M/S


What does it mean when it asks for units of fractional velocity of light?

Speed of light= 299 792 458 meters per second

Welcome to the PF.

(it's best to use the correct capitalization on the units, so m/s is meters per second...)

They asking you to divide the velocity by the speed of light "c" to get a fractional number. Like, if your speed is half the speed of light, it can be written 0.5c
