Need to find distance of an object over an incline plane

  1. Nov 18, 2012 #1
    1. The problem statement, all variables and given/known data


    an object is traveling 30 m/s up a 30 degree incline with height of 20, (there is zero friction) how far did it go?
    2. Relevant equations

    no idea

    3. The attempt at a solution

    stuck

    Since there is no friction, think of why the object would come to a stop.

    because of acceleration due to gravity

    Indeed. So, at which height y (measured vertically, not up the incline) does it stop rising?
