C. A person is leaning against a wall with her hand straight out pushing against the wall. Compare the force exerted by her hand on the wall to that exerted by the wall on her hand. What is the type of force exerted by the wall on her hand called? d. In (c), is the force exerted by the wall on the person's hand passive or ac- tive? Explain. e. In (c) compare the horizontal component of the force exerted by the per- son's feet on the floor to the horizontal component of the force exerted by the floor on her feet. What is the type of force exerted by the floor on her feet called? f. Is the force described in (e) that the person exerts on the floor passive or active? Explain. g. A truck attempts to tow a car. They are connected by a 2-m-long rope. At first the truck doesn't pull hard enough, and the car doesn't move. Com- pare the force exerted by the truck's bumper on the rope to that exerted by the rope on the truck's bumper. Also compare the force exerted by the rope on the car's bumper to that exerted by the car's bumper on the rope. h. Finally the truck pulls hard enough so that the car begins to move. Com- pare the same pairs of forces as in (g) to each other. i. An elevator is hanging from a strong cable. The elevator is at rest. Com- pare the force exerted by the cable on the elevator to that exerted by the elevator on the cable.
