Rolling down a slope vs to slide down a slope

[K^2]

You could also have rolling with slipping... But I suppose there is enough confusion going about without it.

If #3 (vs #1) really is what the OP was looking for, it seems like a confusing and highly contrived scenario to me, but in that case it seems the other answers are correct.

Doc Al's explanation of the cases is correct. Anyway, since I'm so good at asking questions, what is "a highly contrived scenario"? I've tried to look it up, but I can't make sense out of it in my native language. An online dictionary says: "Contrived = Obviously planned or calculated; not spontaneous or natural; labored". A "highly calculated scenario" just sounds wrong to me..
