What I don't know is how can I calculate the minimum kinetic friction that will keep the system from accelerating.

I tried setting the acceleration to zero for this formula:

[Tex] a= 1\ frac{m2*g-m1*g*sin\theta - \mu*m1*g*cos\theta} {m1+m2} [\tex]

after that i really don't get the answer. Please any sugestions.
