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?

A manufacturer has modeled its yearly production function P (the monetary value of its entire production) as a so-called Cobb-Douglas function $P(L, K)=1.47 L^{0.65} K^{0.35}$ where L is the number of labor hours (in thousands) and K is the invested capital (in millions of dollars). If both the amount of labor and the amount of capital are doubled, verify that the production is also doubled.

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.

Suppose that photons of blue light (430 nm) are used to locate the position of a 2.80-g Ping Pong ball in flight and that the uncertainty in the position is equal to one wavelength. What is the minimum uncertainty in the speed of the Ping-Pong ball? Comment on the magnitude of your result.

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?

A certain airplane has two independent alternators to provide electrical power. The probability that a given alternator will fail on a 1-hour flight is $.02$. What is the probability that (a) both will fail? (b) Neither will fail? (c) One or the other will fail? Show all steps carefully.

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 accompanying photo shows a KC-10A Extender using a boom to refuel an aircraft in flight. If the velocity of the $\mathrm{KC}$ $10 \mathrm{~A}$ is $125 \mathrm{~m} / \mathrm{s}$ due east relative to the ground, what is the velocity of the aircraft being refueled relative to the ground.

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

There are 20 first-class passengers and 120 coach passengers scheduled on a flight. In addition to the usual security screening, 10% of the passengers will be subjected to a more complete search.

Explain how you would use a random number table to select the coach passengers to be searched.

It is observed that the skier leaves ramp A at an angle θ = 50 with the horizontal. If he strikes the ground at B, determine his initial speed V and the time of flight t.
