A bear sling, Fig. 4–40, is used in some national parks for placing backpackers' food out of the reach of bears. As the backpacker raises the pack by pulling down on the rope, the force F needed: (a) decreases as the pack rises until the rope is straight across. (b) doesn't change. (c) increases until the rope is straight. (d) increases but the rope always sags where the pack hangs. F FIGURE 4–40 MisConceptual Question 4.

Consider Figure 5.28. The driver attempts to get the car out of the mud by exerting a perpendicular force of 610.0 N, and the distance she pushes in the middle of the rope is 1.00 m while she stands 6.00 m away from the car on the left and 6.00 m away from the tree on the right. What is the tension Tin the rope, and how do you find the answer?
