So I have and inclined plane at 1 degrees, and on top of it, there is an object 361grams. I gradually increase the angle of the inclined plane, and just at 20 degrees, the object starts to slide down. How do I find out the coefficient of friction?(adsbygoogle = window.adsbygoogle || []).push({});

I only know that just before it is about to slide down, mgsin20-Ffmax=0

so do i use 19.99999 degrees to solve this equation?

Any help would be appreciated.

Thanks
