No friction? then the inertia on m1 tending to move it back (m1*a) is pulling on the cord, equalling in tension m2*g
first, what is a:
F=(M+m1+m2)a solve for a.
then m1*a=m2*g
m1(F/(M+m1+m2))=m2g
solve for F, check my math.
Hey.. I don't know exactly how to get the solution for this one...

(its a sketch i made with paint^^)
We assume there are no frictions at all and we only look at the masses M, m1 and m2.
I want to know how much force do i have to give to push M in such a way that it accelerates so fast that m1 and m2 wont move related to M?

Ah great thank you. I got problems with it because there are no frictions...i can hardly imagine how the masses behave but ill get an "eye" for it. Seems very right, big thanks!
