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?-...

(a) An elevator of mass m moving upward has two forces acting on it: the upward force of tension in the cable and the downward force due to gravity. When the elevator is accelerating upward, which is greater, T or w? T w Both forces are equal. (b) When the elevator is moving at a constant velocity upward, which is greater, T or w? T w Both forces are equal. (c) When the elevator is moving upward, but the acceleration...
