Ahhh, don’t you love science fiction?
On rearranging furniture…
A woman exerts a sporadic horizontal force on a couch. As a result, the couch moves across a smooth, hardwood, horizontal floor at a averaged speed vo.
This sporadic, horizontal force applied by the woman:
A) has the same magnitude as the weight of the couch.
B) is greater than the weight of the couch.
C) has the same magnitude as the total forces which resists the motion of the couch.
D) is greater than the total force which resists the motion of the couch.
E) is greater than either the weight of the couch or the total forces which resists it’s motion.
F) who cares? this just means it’s lucky date night!!!!~~!!!!
