A surveyor measures the distance across a straight river by the following method (Fig. P3.7). Starting directly across from a tree on the opposite bank, she walks d = 100 m along the riverbank to establish a baseline. Then she sights across to the tree. The angle from her baseline to the tree is = 35.0. How wide is the river?
The layout of the town of Popperville is a perfectly square grid, with blocks 100 feet long (Fig. P3.8). A cat leaves her house and travels to Mike Mulligans place 4 blocks west and 3 blocks north of its starting point. After lapping up the milk that Mike always leaves out, the cat travels an additional 1 block north and 3 blocks east to Mrs. McGillicuttys house. a. On your paper, carefully copy the grid of streets that contains the cats house, Mike Mulligans house, and Mrs. McGillicuttys house. Then draw and label three displacement vectors on your sketch: r1, the cats displacement from her house to Mike Mulligans; r2, the cats displacement from Mike Mulligans to Mrs. McGillicuttys; and rtot, the cats total displacement. b. Write an equation to relate the three displacement vectors you have drawn. c. Is the distance the cat traveled greater than, less than, or equal to the magnitude of the cats total displacement vector? Explain. FIGURE P3.8

For example, dimensional analysis could be used to determine the number of nickels in 3432.35 dollars. 34 dellar • To begin, write down the starting value, 3432.35 dollars. This can also be written as a fraction: Next, convert dollars to cents. This conversion involves a simple conversion factor: delar Note that the "dollar" unit should appear on the bottom of this conversion factor, since "dollars" appears on the top of the starting value. • Finally, convert cents to nickels. This conversion also involves a simple conversion factor. . This time "cents" should be on the bottom of the conversion factor, S centa since it was on top of the previous conversion factor. • Combining these expressions gives us 1 nickel 5 centa 3432.35 dollars ) (100 cente 1 dollar • Finally, cancel units. Since dollars are divided by dollars, and cents are divided by cents, both of these units can be canceled. Multiplying through gives the final result: 1 nickel 5 centis 3432.35 dollars 100 conts 68, 647…

Assign.#(4)... Estimates and Order-of- Magnitude Calculations a) Estimate the number of breaths taken during an average human lifetime Hint: Let we start by guessing that the typical human lifetime is about 70 years. Think about the average number of breaths that a person takes in 1 min. This number varies depending on whether the person is exercising, sleeping, angry, serene, and so forth. To the nearest order of magnitude, we shall choose 10 breaths per minute as our estimate. (This estimate is certainly closer to the true average value than an estimate of 1 breath per minute or 100 breaths per minute.) b) What if the average lifetime were estimated as 80 years instead of 70? ?Would that change our final estimate
