A man pushes on a piano with mass 180 kg that it slides at constant velocity down a ramp that is inclined at 11° above the horizontal floor. Neglect any friction acting on the piano. Calculate the magnitude of the force applied by the man if he pushes (a) parallel to the inclined and (b) parallel to the floor.
