I have been stuck on this problem for so long... It's seriously driving me insane.(adsbygoogle = window.adsbygoogle || []).push({});

The problem:

An incline plane that makes an angle of 28 degrees to the horizontal is mounted on wheels. A small block of mass m=0.9kg rests on the plane, held there by a coefficient of static friction [mu]=0.73.

The plane is accelerating to the right. What is the minimum accleration in order that the block slides down the plane?

So far I've only been able to draw the free body diagram. After that, I realize I have to apply Newton's 2nd law to the vertical and horizontal components, but that's where I start having trouble. I don't really know how to separate out the components

Any help would be greatly appreciated! Thanks in advance.
