Acceleration of an inclined plane?

  1. Oct 25, 2014 #1
    If I have a ramp that is 1.143 meters long, and I need to make it incline at a certain angle and height to make sure the acceleration is .5 m/s^2, how would I go about doing that without taking friction into account and without weighing anything?

    How might you find the component of the acceleration due to gravity parallel to the incline?

    i am so lost on this, not sure if it's just trial and error or if I can use some type of equation

    do i do a=gsin(theta) where g is 9.8
