Airplane flight plan An airplane flying at a speed of $400 \mathrm{mi} / \mathrm{hr}$ flies from a point $A$ in the direction $153^{\circ}$ for $1$ hour and then flies in the direction $63^{\circ}$ for $1$ hour.

How long will it take to get back to point $A$ ?

Flight engineers for the Apollo Lunar Orbiter placed the orbiter $15 \overline{0} \mathrm{~km}$ above the surface of the moon. What was the Orbiter's (a) linear velocity and (b) period as it orbited the moon? (c) How would increasing the altitude affect the Orbiter's velocity and period?

The altitude (in feet) attained by a model rocket t sec into flight is given by the function $h(t)=-\frac{1}{3} t^{3}+4 t^{2}+20 t+2$ $(t \geq 0)$ Find the maximum altitude attained by the rocket.

Prove these statements: $(a)$ As long as you can neglect the effects of the air, if you throw anything vertically upward, it will have the same speed when it returns to the release point as when it was released. $(b)$ The time of flight will be twice the time it takes to get to its highest point.

In economics, when discussing the factors of production, the term land refers to:
A) farmland
B) real estate
C) capital goods
D) all natural resources.

You allow 40 min to drive 25 mile to the airport, but you're caught in heavy traffic and average only 20 mile/h for the first 15 min. What must your average speed be on the rest of the trip if you're to make your flight?

What is the second step of capital budgeting? a. Gathering the money for the investment b. Identifying potential projects c. Getting the accountant involved d. All of the above

In the following exercise, do the following.

Determine the time the projectile is in flight and the horizontal distance covered.

Tyler McGinnis is playing golf. He hits a golf ball from the ground at an angle of $60^{\circ}$ with respect to the ground at a velocity of 150 feet per second.

A small steel ball is projected horizontally off the top of a long flight of stairs. The initial speed of the ball is $3.0 \mathrm{~m} / \mathrm{s}$. Each step is $0.18 \mathrm{~m}$ high and $0.30 \mathrm{~m}$ wide. Which step does the ball strike first?

Insert colons where they are needed in the following items.

Example 1. The 8 : 15 flight was full, so I reserved a seat on the 9 : 10 .

2. I just finished Undaunted Courage Meriwether Lewis, Thomas Jefferson, and the Opening of the American West.

A satellite is launched with an initial velocity $v_0=4000 \mathrm{~km} / \mathrm{h}$ parallel to the surface of the earth. Determine the required altitude (or range of altitudes) above the earth's surface for launching if the free-flight trajectory is to be (a) circular, (b) parabolic, $(c)$ elliptical, and (d) hyperbolic.

The Neal Company wants to estimate next year’s return on equity (ROE) under different financial leverage ratios. Neal’s total capital is $14 million, it currently uses only common equity, it has no future plans to use preferred stock in its capital structure, and its federal-plus-state tax rate is 40%. The CFO has estimated next year’s EBIT for three possible states of the world:$4.2 million with a 0.2 probability, $2.8 million with a 0.5 probability, and$700,000 with a 0.3 probability. Calculate Neal’s expected ROE, standard deviation, and coefficient of variation for each of the following debt-to-capital ratios; then evaluate the results: $$ \begin{matrix} \text{Debt/Capital Ratio} & \text{Interest Rate}\\ \text{0\\%} & \text{--}\\ \text{10} & \text{9\\%}\\ \text{50} & \text{11}\\ \text{60} & \text{14}\\ \end{matrix} $$

The following statement contains an italicized vocabulary word or related form. Decide whether the sentence is true or false, and write True or False on the answer line.

Some people who live beneath the flight paths of airplanes never become inured to the noise level. __________________________
