A man moves a 170 kg piano with constant speed up a ramp inclined 15.0º above the horizontal. Considering that the coefficient of friction between the piano and the ramp is x = 0.15 and that the force applied by the man is parallel to the ramp, determine: a) The magnitude of the force applied to make the piano go down the ramp. b) In which direction the man should apply the force (Draw a drawing to indicate it)
