Chapter 5, Problem 5.9E
A man pushes on a piano with mass 180 kg; it slides at constant velocity down a ramp that is inclined at 19.0° 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 incline and (b) parallel to the floor.

coefficient of kinetic friction between the box and the floor is 0.266. With what
force does a person need to push the box in order for the box to move with no
acceleration?
