"Cosa provava quella ragazza?"

"What was that girl trying" is also correct. So I am wondering which usage is more common ? trying or feeling ?

'feeling' takes my vote, but it depends on the context. If the girl had just received some bad news then 'feeling' would be ok, but if she was in a heap on the ground you would probably say what was she 'trying' to do.
