Never mind I got it myself. I was wrong in the very beginning. The formula should be Krot+Kcm=Ug. Since energy is conserved meaning that final energy minus initial energy is zero in other words final=initial. The final is the graviatational potential energy since it is stopped and at a...

I am sure that is the correct formula since I looked it up. The only problem is if I am using the angle correctly. I think that I am using the angle wrong. For Ug, the height h should it be what x is or I should include the angle since x is the hypotenuse. So the height should actually be...

Homework Statement A ring (hollow cylinder) of mass 2.30 kg, inner radius 4.35 cm, and outer radius 5.65 cm rolls (without slipping) up an inclined plane that makes an angle of θ=38.0°, as shown in the figure attached. At the moment the ring is at position x = 1.95 m up the plane, its...
