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?

The second mover needs to apply a force equal to or greater than the force of friction in the opposite direction to help push the couch up the ramp. Since the force of friction is 110 N in the opposite direction, the minimum force the second mover needs to apply is 110 N or more.
Therefore, the correct answer is 110 N.
