Isn't it the same?

In the system, the rope is pulled with an force F. The mass of the block is $M$ and that of the wedge $M'$ . The wedge is movable. All surfaces are smooth. The pulley and the rope are massless and frictionless. Find the acceleration of the wedge.

Details And Assumptions :

• $M= 300 \text{ kg}$ , $M' = 350 \text{ kg}$ , $g = 10 \text{m/s}^{2}$ , $F = 1000 \text{ N}$ , $\theta = 60^{\circ}, \sqrt{3} = 1.732$ .
