Best ResponseYou've already chosen the best response.0since friction prevents slipping and frictional force is causing rotation with angular acceleration @ thus torque, T = f*R = I*@

Best ResponseYou've already chosen the best response.0if frictionless [ you did not specify], then same but if they are rolling, the cylinder will be slower as has a greater I [as it is more "spread out" about the rotating axis] to prove that, personally i'd use energy conservation for this rather than forces as its a lot less fiddly
