An elevator with a person in it is being pulled upwards by a massive cable. Identify all interaction forces (consistent with Newton’s 3rd Law) in the system. Specify the object the force acts on. a label for its magnitude and its direction. Consider your system to consist of the cable, the elevator, the Earth and the person. For example, the Earth pulls down on the elevator with force Melevator9 and the elevator pulls up on the Earth with force Meievatorg?- There are four more pairs of forces (when you ignore gravitational forces that do not include the Earth). A 20 kg box on a frictionless horizontal surface is acted upon by two horizontal forces. When the forces pull in the same direction, the box accelerates to the right at 11 m/s2. When the forces pull in opposite directions, the box accelerates to the left at 1 m/s2. Find F-1 and F-2. Note that since I am not using vector notation here, it is implied that I want the magnitude of each of the two forces.
