A mover needs to push a couch up an inclined ramp that makes 21o with the horizontal. If the couch has a mass of 70 kg, and the coefficient of kinetic friction between the couch and the ramp is 0.22, what should be the magnitude of the force parallel to the ramp that must be applied by the mover so that the couch moves with constant speed?
