Homework Statement
The problem is in attached screenshot. Now,I solved this using force/torque method. However ,I got different solution as given in solution manual. Where I have gone wrong?
Homework Equations
The Attempt at a Solution
Applying F=ma to cylinder:
$$mg-T=ma$$
Applying ##\tau = I\alpha## to cylinder about CoM,
$$TR= I\alpha$$
Since the string doesn't slip we have
$$\alpha= a/R $$
Solving the above 3 with ##I=MR^2/2## we have,
$$Mg= 3Ma/2 \implies a=2g/3$$
However,the solution is ##a=g/2##. Where I have gone wrong?
