Homework Help: Physics

Posted by Lindsay on Saturday, December 8, 2007 at 9:24am.

A block weighing 70.7 N rests on a plane inclined at 21.6 to the horizontal. The coefficient of the static and kinetic frictions are 0.23 and 0.12 respectively. What is the minimum magnitude of the force F, parallel to the plane, that will prevent the block from slipping?

I STILL can't get this one. I've tried multiple answers, none of which are correct. Could someone please give me a little help?
