A 70 kg woman pushes on a wall at 35 newtons and recoils. What is the magnitude of the force?

To determine the magnitude of the force with which the woman recoils, we need to apply Newton's third law of motion, which states that for every action, there is an equal and opposite reaction. In this case, the woman exerts a force of 35 newtons on the wall, so the wall exerts an equal and opposite force of 35 newtons back on the woman.

Therefore, the magnitude of the force with which the woman recoils is 35 newtons.
