Homework Help: Stuck with an acceleration problem

  1. May 14, 2013 #1
    I know this is quite simple question.
    An object has an into all velocity of 50m/s it's traveling straight up. Assume g=-10m/s^2 how long does it take to go up and down?

    I put these numbers into x=1/2at^2+vi*t but I still have 2 variables. X and T. Idk what to do.

    Well what does the variables x and t define? Which one would you like to solve?

    Hint: If you start and end at the same position, your displacement is zero.
