Lesson: Newton’s Third Law of Motion

An elevator is accelerating vertically upwards at . A man of mass is standing inside. Determine the reaction force of the floor on the man.

An elevator was accelerating vertically downwards at 1.7 m/s². Given that the acceleration due to gravity is , find the reaction force of the floor to a passenger of mass 103 kg.

An elevator is moving vertically upwards at a constant speed. A man of mass 150 kg is standing inside. Determine the reaction force of the floor on the man. Take .
