Problem
A person presses horizontally against a rigid brick wall with a force of 150N, yet the wall does not move.
(i) Identify the action and reaction forces involved, clearly naming the two bodies and the direction of each force.
(ii) Explain why the wall remains at rest even though a force of 150N is applied to it.
(iii) The two forces found in part (i) act simultaneously. Explain why they do not cancel each other for the person who is pushing the wall.
