Block on an inclined plane, given mass and angle find acceleration

[dhymas]

Homework Statement

A 42 kg block of ice slides down a plane with an angle of 30 degrees. Assuming friction is negligible, what is the acceleration of the block down the incline

Homework Equations

F=ma

The Attempt at a Solution

I have drawn the right free body diagram. I just don't understand where to go on from there. Do I need to find the FnetX and Fnet Y using the angle given? If so where do I go from there?

I really need help. I know I need to find W which is W=(42kg)(9.8) which is 411.6. That gives me W on the free body diagram. Which now I can find the X and Y components using cos30(411.6) and sin30(411.6). I just do not know where to go on from here. I don't know what equation to use once I have W to find acceleration.
