(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

An inclined plane is 30 degrees above the horizontal with a 2 kg ball at the top. Assume no friction or air resistance, and assume acceleration due to gravity is 10 [m/s^2]. Find the acceleration of the ball in the vertical and horizontal.

2. Relevant equations

F = ma

3. The attempt at a solution

So my attempt at the problem is to draw a force diagram of the situation, and then rotate my axis so that the normal force points up, and the gravitational field force points 30 degrees left, like this: http://img49.imageshack.us/my.php?image=yghrtqi6.jpg

So after that it's pretty easy to find the x and y components of Fg (since I know the hypotenuse is 20 N), but how do I find Fn?
