Rotation: Mixed Linear/Rotational Problems

Problem #: 1 | Variant #: 1

An empty metal can rolling down a hill gets to the bottom with a speed of 5.5 m/s. What would have been the speed if the can was full?
(assume the ends of the hollow can don't significantly affect its moment of inertia and the walls are so thin that the full can may be considered as a solid cylinder of the same radius)
