Asked by Mason

Two movers are attempting to push a couch up a ramp. One mover applies a force of 80 N to the right, but the force of friction between the couch and the ramp is providing a force of 110 N in the opposite direction, and the couch slides down the ramp.

At minimum, how much force will the second mover need to apply to help push the couch up the ramp?

Net force now = 80 N (up) − 110 N (down) = −30 N (down). The second mover must supply at least 30 N to cancel that and make the net force zero (any more would move it up). Answer: 30 N.
