Why not? its a hollow cylinder. i forgot to mention that. sorry. but that doesn't really change a lot does it? http://en.wikipedia.org/wiki/List_of_moments_of_inertia first one?edit: i assume that the friction in beta case is not the same as in alfa case, but then again, i don't even need the...

well that's the problem. i know that v = r\omega and i wrote the equations for both rolling and slipping.ma = mgsin\beta - \mumgcos\beta - T I\alpha=rT - rmg\mucos\beta from which I got T = \frac{mg}{2}sin\beta and got the acceleration 0,753 m/s^2. but the problem is that now i get that...

thanx :DWell, if it slips down the plane, then my first equation becomes mgsin\beta - \mu mgcos\beta- T? But now, what to do with the angular momentum? It should stay the same as I wrote it? I mean, I don't have an exact idea of what should I calculate in order to have enough data to find...

Homework Statement A cylinder, with a rope wrapped around it, is placed on top of an inclined plane.If the speed of the cylinder in the bottom of the plane, when the angle of the plane is 30 degrees, is 1m/s, find what speed will the cylinder have when it is placed on a plane with an angle of...
