Well, if the initial blow imparted a sizeable rotation, AND the cylinder was sliding on the ground, (while rotating) eventually the sliding would slow due to the friction with the ground and the cylinder's rotation could contribute to its translational velocity.

Thank You for taking the time to reply.

But, I still don't quite get this. Wouldn't the friction cause the cylinder to have less energy and, therefore, a slower cylinder rotation and a slower translational velocity? Maybe, it is because I don't quite understand rotations involving objects that slide? Currently, I am only dealing with objects that do not slip.
