Question

The two trees in Figure 1 are 6.7 meters apart. A backpacker is trying to lift his 19-kilogram backpack out of the reach of bears.

### Figure Explanation

In Figure 1, there are two trees positioned 6.7 meters apart. A rope is strung between the trees, and a backpack is suspended in the middle. A backpacker is standing beside one tree, pulling down on the rope. An arrow labeled "F" indicates the force being applied by the backpacker in a downward direction. This setup illustrates a method for keeping a backpack elevated and out of reach of wildlife, such as bears.

**Part A**

Calculate the magnitude of the force $\vec{F}$ that he must exert downward to hold the backpack so that the rope sags at its midpoint by 1.1 m.

*Express your answer to two significant figures and include the appropriate units.*

\[
F = \text{Value} \quad \text{Units}
\]

**Part B**

Calculate the magnitude of the force $\vec{F}$ that he must exert downward to hold the backpack so that the rope sags at its midpoint by 0.11 m.

*Express your answer to two significant figures and include the appropriate units.*

\[
F = \text{Value} \quad \text{Units}
\]
