Question

block 3M slides downward without friction. The string connecting blocks 3M and M is ideal (that is, its mass can be neglected and it is not stretchable). The pulley, a uniform solid disc of mass M and radius r , rotates without slipping. Find the acceleration of block 3M.
(2*g/9)(3sin(theta)-1)
Hi enjoy,I got (2*g/5)(3*sin(theta-1) which is not in options.. Can you please show me how to get 2*g/9? I appreciate your help.
In question no.2 a) torque would be 2*F*r/2? I am confused that from top view, which force we have to use?
a) alpha= 2F/mr ccw
b) alpha= 2F/mr cw
c) alpha= 8F/3mr ccw
