While sliding a couch across a floor, Andrea and Jennifer exert forces FA and FJ on the couch. Andrea's force is due north with a magnitude of 150.0 N and Jennifer's force is 27° east of north with a magnitude of 190.0 N.
(a) Find the net force (in N) in component form.
(b) Find the magnitude (in N) and direction (in degrees counterclockwise from the east axis) of the net force.
(c) If Andrea and Jennifer's housemates, David and Stephanie, disagree with the move and want to prevent its relocation, with what combined force Fos (in N) should they push so that the couch does not move? (Express your answer in vector form.)
