Homework Help: Object accelerated at one G for one year

  1. Aug 23, 2012 #1
    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...) :smile:

    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
