Question

A man pushes against a rigid, immovable wall. Which of the following is the most accurate statement concerning this situation? The man cannot be in equilibrium since he is exerting a net force on the wall. If the man pushes on the wall with a force of 200 N, we can be sure that the wall is pushing back with a force of exactly 200 N on him. Since the wall cannot move, it cannot exert any force on the man. The man can never exert a force on the wall that exceeds his weight. The friction force on the man's feet is directed to the left. The work energy theorem says the net work done plus the final kinetic energy is the initial kinetic energy. the net work done plus the initial kinetic energy is the final kinetic energy. Final kinetic energy plus the net work done is the initial kinetic energy. The net work done minus the initial kinetic energy is the final kinetic

1) B) By Newton's II law

2) B) Ki + Wnet = Kf
