My text book is not helping me on this, so I'd love some help. A cylinder is rolling down a ramp, without slipping. I have the total kinetic energy, but now need to know the rotational kinetic energy and transitional kinetic energy at the bottom of the ramp. I have the mass, radius, length, w, v, and I of the cylinder and the height and length of the ramp. I know it should be super easy at this point, as I know the total energy. But nothing's working. HELP! I have that: KE tot = 1/2 I x w^2 + 1/2 m x v^2. Any guidance?
