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.)

Is a  vector quantity  that refers to "the rate at which an object changes its position." imagine a person moving rapidly - one step forward and one step back - always returning to the original starting position. while this might result in a frenzy of activity, it would result in a zero velocity. because the person always returns to the original position, the motion would never result in a change in position. since velocity is defined as the rate at which the position changes, this motion results in zero velocity. if a person in motion wishes to maximize their velocity, then that person must make every effort to maximize the amount that they are displaced from their original position. every step must go into moving that person further from where he or she started. for certain, the person should never change directions and begin to return to the starting position.

Work is reduced while time is decreased
