A man pushes on a piano of mass 180 kg so that it slides at a constant velocity down a ramp that is inclined at 11° above the horizontal. No appreciable friction is acting on the piano. Calculate the magnitude and direction of this push if the man pushes parallel to the incline.
34.3 N up the incline 337 N up the incline 337 N down the incline 34.3 N down the incline
