a gardener pushes a wheelbarrow.

Question

according to Newton's third law the barrow's reaction force on the gardener is the exact opposite of her force on the barrow. a bystander concludes the gardener and barrow will not move because they push equally against each other. how can i explain to him why the gardener and barrow will move?thx.

The net force is zero. So there is no acceleration. What does that have to do with Newtons first law?
