Error in upcoming quiz?

correct me if i’m wrong but question one of end of section 4 quiz’s answer is 2000 Newton seconds as impulse. Shouldn’t it be Js or are they the same thing?

A Joule is a N•m (Newton meter). N•s is just Newton•seconds, so I think the question/answer is correct… 1000 N applied for 2seconds would be 2000N•s.
