Vector upper a overscript right-arrow endscripts has a magnitude of 69 units and points due west, while vector upper b overscrip
Tom [10]
Refer to the figure below.

Define unit vectors as follows:
\hat{i} in the eastern direction
\hat{j} in the northern direction

Given:
Vectors a and b point due west and south respectively. Therefore
\vec{a} = -69 \ht{i} \\
\vec{b} = -69\hat{j}

Part (a)
\vec{a}+\vec{b}=-69\hat{i}-69\hat{j}=-69(\hat{i}+\hat{j})
The magnitude is
|-69(√[1² + 1²])| = 69√2 = 97.58.
The direction relative to west is
θ = tan⁻¹ (b/a) = tan⁻¹ 1 = 45°  south of west

Answer:
The magnitude of (a + b) is 97.58 or 69√2.
The direction is 45° south of west.

Part (b).
\vec{a} - \vec{b} = -69\hat{i}+69\hat{j}=-69(\hat{i} -\hat{j})
The magnitude is
|69(√(1+1)| = 69√2 = 97.58.
The direction relative to west is
tan⁻¹ (b/a) = 45° north of west.

Answer:
The magnitude of (a-b) is 97.58 or 69√2.
The direction is 45° north of west.

An engineer is designing a roller coaster. The tallest peak is 310 feet high.
rusak2 [61]
<h2>Hello!</h2>

The answer is:

The slope of the hill is equal to 2.

<h2>Why?</h2>

To solve the problem, we need to remember that the slope of a line, is the rate of increase or decrease of the line.

From the statement we know that the tallest peak of the roller coaster is 310 feet (y), while the roller coaster travels 155 horizontal feet (x), so, calculating we have:

Slope=\frac{height}{base}=\frac{y}{x}

Then, substituting the given information and calculating, we have:

Slope=\frac{310ft}{155ft}=2

We have that the slope of the hill is equal to 2.

Have a nice day!
