1. The problem statement, all variables and given/known data A man pushes on a piano of mass 180kg so that it slides at a constant V of 12.0 cm/s down a ramp that is inclined at 11.0 degrees above the horizontal. No appreciable friction is cting on the piano. calculate the magnitude and direction of this push if the man pushes the piano up the plane instead, also at 12 cm/s parallel to the incline. if the man pushes the piano horizontally, but still with the speed of 12.0 cm/s? 2. Relevant equations F=ma 3. The attempt at a solution I've already drawn the free body diagram, but i can't find anywhere what to do if the object is pushed. does the vector point toward the object, or away from the object in the direction it is being pushed? and if V is constant, then that means no acceleration, so doesn't that mean no force in the direcion of the push? regardless of what direction the man pushes (parallel to ramp or horizontal)?
