is it like this
A Block of mass M1 is kept on a Triangular wedge of mass M2 which is again kept on a larger triangular wedge of mass M3.How can we find the net acceleration. All the surfaces are Frictionless.

yes. exactly like dat but plz give the xplanation of the answer in detail.
satrap i will give u three hints:
1) Wedge moves in horizontal direction.
2) Mass M1 moves along the surface of wegde with respect to the wedge!
3) most importantly: mass M3 moves in vertical direction (try to reason out why!)
Now try to solve these out using the basic law: F=ma
Will await u to see ur reply with the successful answer or more importantly DOUBTS! [1]
Dont hesitate to ask ur doubt out in the fear u will be branded a fool..
coz in case u dont.. u ll remain a fool forever!
So feel free to ask doubts here! [1]
I think the smaller wedge will slide down with acc=gsintheta n the smallest block will fall down and slip behind the smaller wedge with same acc due to absence of friction.
This problem just ticks into the place where you need the think for the constraint equations.
