A plane descends to sea level from $12,000 \mathrm{ft}$ after being airborne for $1 \frac{1}{2} \mathrm{hr}$. The entire flight time is $2 \mathrm{hr} 10 \mathrm{~min}$. Find the average rate of descent of the plane.

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.

Consider the motion of the following objects. Assume the x-axis points east, the y-axis points north, the positive z-axis is vertical and opposite g, the ground is horizontal, and only the gravitational force acts on the object unless otherwise stated.

Determine the time of flight and range of the object.

A man of mass $80 \mathrm{~kg}$ runs up a flight of stairs $20 \mathrm{~m}$ high in $10 \mathrm{~s}$. (a) how much power is used to lift the man? (b) If the man's body is $25 \%$ efficient, how much power does he expend?

Which industry or sector of the economy would least likely be affected by the business cycle?

A. Automobiles

B. Consumer durables

C. Capital goods

D. Services

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?

You have a 3:30 P.M. flight to New York. It takes 1 hours to check in at the airport and board the plane. It takes 45 minutes to drive to the airport and park the car. At what time should you leave your home to drive to the airport?

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. __________________________

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.

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

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.

Use your TI-83/89 to analyze the paper airplane flight distance data from the mentioned activity.

First, enter the data into your calculator and explore the data graphically. Does it appear that at least one of the means is different from the other means?

Explain what a post audit is and how it can provide useful input for future capital investment decisions, especially those involving advanced technology

Describe and illustrate in a graph what happened in the economy in Table 1 if in year 1, capital per hour of labor was 30 and in year 2 it was 40.
